Pandora gets better and better the longer you listen to it (and add groups you like & click dislike on songs you don't like.) I couple probably listen to it for 24 hours and not hear a song more than once or twice, and not have to click "dislike" more than once or twice either. Although, occasionally it plays songs I like, but am not in the mood to listen to. Oddly, it seems that if I skip 2 or 3 songs in a row, that problem doesn't continue.
