Mysterious ghostly voice in Budokai 2

[90sDBZ]

On Budokai 2 on the first map of Dragon World if you let the music play to a certain point a weird voice says something that sounds like "You know I don't like to do that". It's pretty quiet but if you listen you can make it out quite clearly.

Has anyone else ever noticed this? It's been bugging me for years everytime I play the story on that game. Here's a clip of it:

Go to 5:19 and you'll hear it. You hear it every time the music reaches that point.

[Cold Skin]

It's probably part of the BGM, since you say that it happens everytime at this specific point of the track.
It's not the only time you can hear some unknown voice saying or whispering something in tracks of the Budokai game series.

[BlazingFiddlesticks]

It's part of the music. Odd choice, but it is the music.
