Yeah, that's the problem. If the song is known either because its a previously published song or because it repeats then the bits should be the same every time the song is played. If you are adding extra data with steganography then you don't want it easy to detect because someone could make a steganography detector by testing if the same song's data seems to vary for no reason.

I guess you could also build an auto-auto-tune or auto-remix solution so the songs always have justifiable variation without needing fully generated music.

I know next to nothing about steganography, beyond the general concept, so please excuse my ignorance if I'm way off base, but couldn't you design the encoding system such that you could encode the same amount of data within the time frame of each loop, with only some portion of the new data containing real data (audio recording)?

Yes
