If i was a teenager again I'd have this site running in the background all the time.
If you like a song, you can click a button to add a blog post on blogger, livejournal, wordpress, typepad, myspace or xanga. The post it creates integrates the flash music player inline. So your adoring fans can play the song while they read the rest of your blog.
It's not easy to just hit "play" and let it drive, though, the way you can with something like pandora. You can listen to playlists that folks have assembled, but for now I'm just playing a tune and then clicking something at random from the "more music" list on the page. I tried the genre listings, but when I selected Jazz, instead I got some crappy soul music in a weird language ... then again, some folks would probably argue that's the definition of the stuff.
