I am in love with iTunes genius feature.  First, if there is a song you particularly like just click on the song then click on the genius icon and voila!  iTunes makes an entire playlist of songs that mesh well with the song you chose!  Also, it suggests other songs that would go well with your library that are not currently in your library.  And, other songs of that particular artist that are not in your library.  Ahhh....this makes it so much easier to get cool music.

Yea for iTunes!!  Hopefully it will still be around after this whole ordeal with the music industry goes down...
