Songs messing up in brawl

[Cacapiko]

I recently tried replacing the songs in luigi's mansion with kingdom hearts songs (replaced it with a KH stage).
and for some reason the Castle theme and airship theme, work fine, but every time i put a brstm on the luigi's mansion theme, tetris type: A and B, it just cuts away mid-song and starts playing some random song from another stage, or another song from the same stage. It doesn't seem to be the brstm file's fault, as much as the stage's fault, anyone know how to fix this, its happened to me before.

Copy it all to your PC and format the SD. Then move it all back inside. SD Cards sometimes screw up with Sounds, and formatting fixes it for me.
