I find it really hard to classify music by genre when I'm only allowed to select one genre. Is it hiphop or R&B. Is it metal or hard rock? It would work so much better if one could select each of the genres a song is suited for. Then, you could select the rock genre and get all kinds of rock. Has someone found a way around this annoyance in iTunes, or is there another media player for the Mac that might handle this better?
