One invaluable find for a music lover is Pandora. If you haven’t seen it, you should check it out. It allows you to specify a favorite band/artist as a starting point, and plays music in the same genre. It learns your tastes and is a great way to learn about new artists; especially if like me, you have a knack for for non-mainstream music.

I just discovered another cool service called Musicovery, which does much of the same thing but has a very cool interface that allows you to visualize similar artists in a map-like layout.
