Web 2.0 - Pandora

A friend of my had recommended Pandora an internet radio site, so when I ran across it on the list, I decided to try it. It is great. After you register, you can create your own radio station based on a song or artist and then the site will play create a station that plays the music and music that the music genome project thinks is similiar. You have some control over what gets played on that station. If you don't like a song, just mark it and it won't ever play on your station again. You can also share stations with friends, get an app for your iphone etc. I'm not sure there's much application for the library, but I'm listening to it as I write this post and enjoying the ability to listen to music.
