Is there any downsides to passing an audio pointer from ARM9 to ARM7 for the music to play, or would it be better to pass a command to play that audio piece specifically?

You'll need to make sure that the ARM9 flushes its data cache (use DC_InvalidateRange) after writing to any memory that the ARM7 can see. You'll also need to make sure that the ARM7 doesn't see a structure that the ARM9 has only half filled in.
