Notably, in formats that have containers (Ogg, et al) just finding the  
data that's "not the tags" isn't sufficient (like it would be for MP3)  
since changes at the beginning file can require changes in all  
subsequent blocks.  libsndfile is probably the thing to look at  
(though it will give you actual audio data, not compressed data).
