Have anyone researched possibility to use a fractal compression
(IFS) to music.
I can see that music contains a lot more selfsimilarities than
pictures; for example listen to disco hit music.
Same thing with some symphonies.

It might be possible compress a file by checking those 'same'
waveforms and save one of them and store others as relatives to the
saved waveform -- because between the saved and others have a minor
differences it needs only few bits to store those relative waveforms.
(Huh, got that? My English is not good; well, you might noted that
allready. :-)

Maybe 1:2 compression ratio... or worst.
