So if you're away from your music, or just looking for a change... check out Pandora. It's awesome, you can start by choosing a song, artist, or genre, and they will play songs based on the type of music you like. I created a 'station' called "Green Day Radio". Since I'm such a huge Green Day fan, it's fun to hear other artists (as well as Green Day) that have similar sounds.  If you're not digging the track they are playing, skip to the next. Very cool, and very good sound quality considering it's all streaming over the internet through your browser.

You can see some of the other stations I created below: U2 Radio, Barenaked Ladies Radio, The Crystal Method Radio, Galvanize (Chemical Brothers) Radio, and of course the Green Day one. Very cool site. It's kind of creepy how good of a job they do of matching other artists to the stuff you like.

I just checked and this works in Safari! With an unlimited data plan, it will be interesting to see how this is going to work on the iPhone.
