I keep a tight ship on my iTunes library with Artists and Albums correctly tagged, album art embedded, the correct year labeled (perfect for creating smart playlists for the decade you're in the mood for)... I even have lyrics for almost all my songs.....but alas, a well kept genres list seems to elude me. I've done some Googling around but I haven't found a solution to this. Does anybody know of a Genre analyzer or if that's even possible? It would be great if there were an app that could comb your library and tag your songs with the correct genre. While I'm at it, is there a BPM analyzer that would do the same but for beats-per-minute?
