possible to downsample music/sound in Jet Grind Radio?

[hrb2k]

yeah, i might try changing music in crazy taxi 2 sometime.

and the music in jgr is pretty cool. i might re-encode the adx files to a higher khz. maybe 22khz/mono. it'll prolly up the size to 400-410MB?? at least i can fit 1 other game in there.
