Pandora

I'm really loving Pandora.com. I found them a few weeks ago while I was just searching on Google, and now I listen all the time. If you haven't heard about Pandora, they're the new web 2.0 music-listening station, where you guide them by telling them a few songs or artists that you really like, and then they respond by choosing other music that they think you'll like and then you tell them your opinion. In that way, your stations "learn" over time. You should really check it out if you haven't already. It's one of the few websites that I really frequent.
