Where can I find these music pieces?

[Saiyajin no Tatsujin]

In DBZ episode #120 of the Japanese version ("Freeza Halved By a Single Blow!! Another Super Saiyan"), where can I find the music that plays when Trunks turns into a Super Saiyan in front of Freeza and King Cold, and also right before he slices Freeza up with his sword? It's a very 80's style pop piece with a whaling guitar in it.

Also, in episode #122 of the Japanese version ("My Dad is Vegeta... Confessions of the Mysterious Boy"), the eerie organ music that plays when Trunks is telling Goku about the Cyborgs? The same organ music can be heard during Vegeta's nightmare in episode #124 ("I Will Overcome... Goku!! The King of the Fighting Saiyan Race").

Thank you in advance to anyone who can help me.

Just by your description, I'm pretty sure the first song is the classic Battle Point Unlimited. Not sure about the second song.

Thanks, Pokewhiz7. I'll check it out.

BP∞ was only ever released on Dragon Ball Z Hit Song Collection Vol. 6.

The second piece you mentioned is M1120A, which is unreleased. You can listen to it here.

Based on this handy dandy guide for all of the music ever... http://kenisu.webs.com/ Second one looks like it's an unreleased track originally from Movie 4, called on here "Slugg Goes Giant (Movie 4, Alternate)"

Now I stop being helpful and tell you that I have no idea where you could find it.
