This thing is the most awesome thing in existence. It's free, you get a 30-second commercial or two every few songs, but you get to customize what you listen to, to a great degree.
You choose a certain amount of bands you like, and it will play songs based on their genre, and similar bands that fans of the same bands recommend.
If you like the songs, you rate them, and the player finds more music like that. If you hate it, you tell it to never play it again.
I'm loving this shit. It's got a fairly good library too.
