For those of you with an iPod, check out the new iTunes version 7.0. The coolest thing (besides an updated look) is a feature called Cover Flow wich allows you to view your collection as if it were a jukebox! Check out this screenshot off my iTunes collection!
I must warn you this new version does have some known issues. So if your the gambling kinda guy, download this baby otherwise wait for the next iTunes update which is sure to fix some of the known issues.
