There is software for converting recorded music to scores. MIDI files are easy; most score software can import them. Regular sound files, such as the OGG files of MSM, are harder to parse. There is software that can do it, but I don't know if anything is free and good. The stuff I've glanced at tends to be expensive, and I don't know how well it works. I don't think software can yet parse complex multi-instrument multi-voice sounds like what one hears output from the game.
