"Like Last.fm and Pandora, Jango immediately creates a personalized radio station with songs by similar artists...But unlike the case with many of these other services, it's super easy to tailor your station—if you don't want to hear a particular artist, click the trash can icon; if you hate a particular song, rate it with a sad face and it'll never play again; if you want to add another main artist around which the station will be built, click "edit station", then enter the name of the artist." [Digital Noise]

Similar to Last.fm and Pandora. Slacker will have its own portable device and satellite car dock allowing mobile access.

Similar to Last.fm, Pandora lets you create custom radio stations by entering a song or artist that you like, and Pandora responds by playing songs it thinks are musically similar. You can guide Pandora by approving or disapproving of the songs it plays, and the system takes this into account for future selections.

Type in an artist you like and Last.fm creates a "station" that plays music similar to it that others have liked. Once you have played enough artists, Last.fm will let you know who your musical neighbors are. You can listen to their "stations" for free. If you sign up (for a small monthly fee) you can play your personal "radio" or your tagged items. Great for discovering new music, and also keep track of hard to find artists by tagging them.
