As someone who listens to EDM (electronic dance music) almost exclusively (though, I'm no DJ or producer) the vast majority of those sounds come from some sort of midi type software or machine be it a drum machine, sound effects machines or software, or recordings of sounds that occur around us. EDM music also has a build up - the beat generally starts simple and gets more complex as the track progresses. Sometimes, thats called the drop, right? When a track builds up, they "drop the beat" and the best gets more complex, as found in Dubstep. So, I think compression like that might work in software they use to write / develop a track; if the software can determine that 2 notes or beats are identical, it could code the file with less data in it, but I think of music to be similar to water. It's fluid, with each note / beat / voice effecting the notes / beats around it. Ever listen to a track with the voice removed? Or with the drums removed? It sounds very different then when the track untouched. Point being, I don't think this would work for a final mp3 or lossless compression. (or I may be completely wrong)
