Drama cassettes contain the entirety of sound for DBZ movies so not just the music but the sound effects and voices as well. The following movies have been released on those tapes: 1, 2, 4, 6 and 11. Since I don't own all of those tapes, I will only focus on those which I own. I haven't got the tape with the audio for DBZ Movie 1 in its shortened version called Koro-chan Pack (and I suspect that the full edition does not exist), the shortened Movie 4 cassette and any version of Movie 6 and 11. The only thing that I know about the Movie 11 tape is that the music is in stereo and there are no differences in content. The shortened tape with Movie 1 also contains the score in stereo since it's labelled as such on the cover of the book included to the tape. I know nothing about any possible differences in the content itself for the cassette. And there's the Movie 6 tape that not only has the music in stereo but 2 alternate musical tracks different than what was used in the movie proper. Also, I know nothing about the shortened Koro-chan Pack versions of Movie 4 and 6 tapes since they haven't joined my collection yet.
Thus I own 3 tapes with the audio for DBZ Movies: the full version of Movie 2 cassette, the shortened version of that same movie and the full version of the drama tape for Movie 4. The sound on these tapes is in mono just as it is on other releases with these movies. Also, the tape with the sound of almost the entirety of Movie 2 is not a bit different from the audio for this film on DBox except for one scene, which was cut out for the tape. However, I will write about the audio differences not in the number of channels since it's the same but in CONTENT in the case of the shortened Movie 2 and the full Movie 4 tapes! Let's get over the discrepancies!
EDIT: As of now, I own 4 tapes with movie audio, the fourth one being the cassette with the full audio from Movie 6. I will be mentioning differences in the number of channels after all.
EDIT: (16.01.2023) At this point I already have all the drama tapes with audio from the movies. Now all the tapes which in any way differ in sound from the movies themselves are included in this thread.
"Koro-chan Pack: Dragon Ball Z – Theatrical Movie Special"

This is the first Dragon Ball tape which contains re-mixed sound. There had been 4 drama tapes before this one. However, the first three contain a completely new material so there are dialogues that were produced exclusively for those tapes mixed with already-existing sound effects and music on those cassettes. Therefore they haven't mixed only materials that were readily available at the time in the case of the first 3 tapes. The fourth cassette contains only already-existing materials and nothing else but those haven't been re-mixed at all and instead they were taken from the anime as-is, in the exact same form as they had been featured in on the show. The tape that is described below features only readily-available materials, which are dialogues, sound effects and music but those elements have been re-mixed this time around!
The movie 1 drama tape has been incorrectly labelled as "STEREO". Only the vocal songs are in stereo but Kikuchi's music and the remaining elements are in mono. So it should have been labelled as "MONO-STEREO" or "STEREO-MONO" like the two movie drama tapes that succeeded this one and the episode 2 tape that preceded it as those cassettes also have some fragments presented in stereo and some in mono.
However, the mistake in labelling of this tape could have been caused by this one exciting moment, which is in stereo! This is the only case in the movie drama tapes, in which the drama part (the one featuring the story) that is always presented separately from the song part is heard simultaneously with the song part, which is always in stereo. So dialogues and sound effects from the always-mono drama part are featured during a vocal song, which means they have mixed those elements in music in stereo. Of course, on the tapes with movies 6 and 11 there are also dialogues and sounds incorporated into the stereo music. However, in those last two cases that is Kikuchi's music and in the case of this tape it's a vocal song. So this moment of this cassette is truly an anomaly in the world of the DBZ movie drama tapes. In the film itself, of course, the insert song "The World's Greatest Gohan" is in mono and on the tape it's in stereo and the same dialogues and sound effects can be heard. That is our first difference:
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
The difference number two is about several lines of dialogue and sounds being removed from the tape but they are featured during the insert song in the original movie presentation:
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
In the insert song there are voices and sound effects that can be heard in both media. However, they are placed in completely different moments of "Tenkaichi Gohan". In the film some pieces of dialogue and sounds are present near the end of the first verse and during the first chorus and on the tape these same elements are featured between the first chorus and the second verse (in the bridge of the song). Moreover, one instance of the sound of the moving cuckoo clock and Gohan sounding like a cuckoo was cut from the cassette and is heard only once there while in the movie there are two instances of these sounds:
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
The last difference in the song "The World's Greatest Gohan" and the forth one on this drama tape. Once more, the same lines can be heard in the movie and on the cassette albeit in different places. But this time these voices are featured during the end of the song in the original film and after the song ends on the tape!
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
All the remaining differences are concerned with the fact that Kikuchi's music is placed differently in both media. The first example of this is below. The cue begins earlier on the tape and later in the movie:
http://matela.stronazen.pl/wp-content/u ... ence-5.mp3
http://matela.stronazen.pl/wp-content/u ... ence-5.mp3
The sixth one! Shenlong's and Garlick Jr.'s theme starts clearly earlier on the cassette than in the film. Also, on the drama the entire BGM track isn't presented because it's heavily cut as the scene itself while in the theatrical version the full cue is there:
http://matela.stronazen.pl/wp-content/u ... ence-6.mp3
http://matela.stronazen.pl/wp-content/u ... ence-6.mp3
Another example of a piece of music being placed on the tape earlier than its film counterpart. And once again it isn't played in its entirety with the scene with it being severely edited as well.
http://matela.stronazen.pl/wp-content/u ... ence-7.mp3
http://matela.stronazen.pl/wp-content/u ... ence-7.mp3
The 8th difference is nothing new here, the track is featured earlier on the cassette. However, there's one interesting bit here. Since the cue begins on the tape half a second before it originally does, it also ends sooner. And after the piece on the drama the sound of Gohan peeing is cut out while it is heard at the very end of the BGM in the theatrical presentation because the music ends later there. However, it doesn't end so much earlier on the cassette for the voice of Kuririn worrying not to be included during the track. This instance of Kuririn's voice is edited out from the tape and in the movie it's featured near the end of the Kikuchi composition:
http://matela.stronazen.pl/wp-content/u ... ence-8.mp3
http://matela.stronazen.pl/wp-content/u ... ence-8.mp3
This one is something new because the track on the tape kicks in later than in the movie! Due to M814 starting later on the drama cassette, there is a short break between this cue and the previous one. In the film the piece begins immediately after its predecessor so there is no moment of breath between the two compositions:
http://matela.stronazen.pl/wp-content/u ... ence-9.mp3
http://matela.stronazen.pl/wp-content/u ... ence-9.mp3
The tenth difference begins just as the ninth one does, i. e. a track (M816) on the tape starts clearly later than in the movie and thanks to this, on the cassette there is a noticeable break between the pieces, which cannot be said about the theatrical audio. On the other hand, on the drama more than a half of the cue is cut out due to the scene it plays in being considerably shortened when in the film one can hear the Kikuchi piece in its fullest:
http://matela.stronazen.pl/wp-content/u ... nce-10.mp3
http://matela.stronazen.pl/wp-content/u ... nce-10.mp3
The penultimate discrepancy is refreshingly different than many of the previous ones. In this case, there is more of a track included on the tape than in the film! In the latter a piece labelled as M817 is very heavily edited out but in the former medium only the end of the cue is removed. Also, it starts slightly earlier than in the movie:
http://matela.stronazen.pl/wp-content/u ... nce-11.mp3
http://matela.stronazen.pl/wp-content/u ... nce-11.mp3
The last one is among the most interesting ones. On the cassette they used an alternative version of the final track of the movie, a quicker one called M819A. In the film M819B was used, a longer and slower arrangement of this cue. Therefore this marks the first case in which an alternate piece is being utilized on the drama tape. And there will be many cases like that in the following installments!

"Koro-chan Pack: Dragon Ball Z The World’s Strongest Guy – Songs and Stories"

This tape doesn't like Oolong... The differences between this tape and other releases can only be heard in the scenes which feature my favourite character from the Hunt for the Dragon Balls arch, the pig himself. Have a listen!
In this scene, you can hear Oolong's voice on DBox while it was cut out on the tape:
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
In the next scene, Oolong's voice was cut out again and this time he took others with him since Piccolo's and Gohan's voices were cut out on the tape while their lines are present in the movie:
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
Another difference is similar: the voices of Gohan and Oolong present on DBox cannot be found on the tape in the scene below:
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
This difference is the most interesting. First of all, Oolong's voice was cut out as usual. But besides that the music in this scene begins earlier than on DBox. Notice how on DBox Gohan breathes out first and the sound of the chair is heard right before the music while on the tape the music kicks in before the gasp and the sound. So consequently, on the cassette, Gohan finishes talking about what could've happened to Piccolo later - when only the last series of notes is left until the end of the track - on Dragon Box, Gohan stops talking in the middle of the second series of notes from the end:
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
Here is the usual absence of Oolong's voice on the tape. And once more the music kicks in earlier on the drama tape than on DBox. That's why when Dr. Wheelo's monsters leap to attack, the music still plays for a moment while on the drama version, the music cannot be heard once the sound effect of the leap begins:
http://matela.stronazen.pl/wp-content/u ... ence-5.mp3
http://matela.stronazen.pl/wp-content/u ... ence-5.mp3
The last difference is obvious: who else but Oolong didn't lend his voice on the tape despite his original line being quite lengthy. Compare:

"Dragon Ball Z: Super Saiyan Son Goku – Soundtrack-Drama Compilation"

In the case of this tape, the changes amount to only 4 and all of them are of musical nature.
The first one is that on the tape, they've used the full version of a track that plays in the scene below. On DBox, a fragment of this cue was cut out. On the tape, 2 series of notes are simply repeated and on DBox each can be heard only once. As a result, when Gohan screams in the movie version, there's no music to be heard anymore while the tape still features Kikuchi's composition well after the scream:
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
The second change that they made for the tape is that it features an alternate version of a track heard in the following scene. The difference between the two is kinda subtle but when you listen closely to cymbals in both, you can hear they are performed differently for the first half of both tracks. In the drama version of the cue, the cymbals are played faster in moments and more cymbal beats can be heard than in the DBox audio:
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
The third difference is not about the additional musical material on the tape, but in fact the absence of some music! In the scene below, the middle part of a cue can be heard on DBox. There's simply no music here on the tape:
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
The last alteration that was made is that the ending song for the movie was delayed on the tape. This resulted in the song starting right after Kamesennin's little work-out on the cassette while on DBox the ending theme kicks in long before The Turtle Hermit stops talking:
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
"Dragon Ball Z: Clash!! 10,000,000,000 Powerful Warriors – Soundtrack-Drama Compilation"

Here, like in Movie 4, differences are concerning music. There are as much as 7 differences in Movie 6!
First of all, this is the only difference not connected with content. It's about the music on the Drama tape being in stereo as opposed to mono on DBox. Please keep in mind that only the score is in stereo and sound effects and voices are still mono. Still some unreleased music can be heard in stereo here, like this cue:
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
http://matela.stronazen.pl/wp-content/u ... ence-1.mp3
The next difference is about the placement of music in relation to voices and sound effects. On drama tape you can hear that famous Goku's "khh" sound at the same time the music kicks in. However, on Dragon Box the expression of pain comes after the second note of the track. Meaning that the music starts playing earlier on DBox than on the cassette. That's why on DBox the tune ends and you can still hear the Super Saiyan aura sound while in the dramatization the sound stops and the music can be heard after that. Speaking of the SSJ aura sound effect - notice that on DBox you hear the sound after Goku is heard starting his transformation with this other famous SFX. Now on the drama tape, there's this aura sound faintly being heard BEFORE the transforming sound. So Goku was sounding like Super Saiyan before really changing into one? Weird.
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
http://matela.stronazen.pl/wp-content/u ... ence-2.mp3
Another difference between the two releases is that in the original movie the following cue gradually fades in while on drama tape it can be heard in its full volume from the start. Also the music again starts earlier on DBox so there's a longer silent gap between the sounds of the scene ending and the next scene beginning. That silence is shorter on the tape as the track is playing until later into the first scene:
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
http://matela.stronazen.pl/wp-content/u ... ence-3.mp3
Difference number four is good ol' usage of an alternate cue. Tracks with different beginnings play in the scene. Also, unsurprisingly, the music kicks in earlier on DBox once again!
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
http://matela.stronazen.pl/wp-content/u ... ence-4.mp3
Here's another example of an alternate track being used. This time the music plays at exactly the same time in both versions. How refreshing...
http://matela.stronazen.pl/wp-content/u ... ence-5.mp3
http://matela.stronazen.pl/wp-content/u ... ence-5.mp3
Another difference is more of the same... Placing the music later in the drama tape. I like this one because on DBox the peaceful track can be heard virtually in its entirety while in the dramatization, due to the cue starting later, it's cut by the thud of Goku and Vegeta falling. So the comedic timing is actually more effective in the tape:
http://matela.stronazen.pl/wp-content/u ... ence-6.mp3
http://matela.stronazen.pl/wp-content/u ... ence-6.mp3
And lastly on DBox the ending song starts after the sound effect of the spacepod is no longer heard. On the cassette the closing theme begins still when the ship sound is present there. What a shock! The music actually is played earlier in the drama tape for once...
http://matela.stronazen.pl/wp-content/u ... ence-7.mp3
http://matela.stronazen.pl/wp-content/u ... ence-7.mp3
That's all. I hope you like all the samples and comparisons. I think it's quite interesting how they've changed things for those tapes so that their existence can be slightly justified. Enjoy!
