geeky musings; or, I hung out with too many DJ's this weekend

I wonder if it's possible, through wave analysis (IE the fast-fourier transformation), to figure out the BPM of a song. Because then you could run it, and have your MP3s sorted by folders or playlists named 120BPM, 130BPM, etc. Then if you wanted to mix stuff it would be easy.
