Well, it plays music, and at first it seems nice to create your own channels based on a band or artist, or even on just one song. But a big problem seems to be with the tweaking for personal taste. As you rate more and more songs with a thumbs-up, its algorithm(s) seem to be so unsophisticated that it just keeps playing the songs you have already rated thumbs-up over and over again, so soon enough even on shuffle setting it becomes less and less like listing to a station than being trapped in you own old record collection, all your own CDs, LPs and 45s, with next to nothing new being played or surprising you. I might try removing all of my thumbs-ups and rather only rate songs I don't like thumbs-down, to see if maybe it can learn to play songs I have never heard before or hardly at all, that I will probably like. I just don't need to hear Smooth Operator and Gimmie Shelter over and over again every time I turn on Pandora, even though I've given both a thumbs-up for being good tunes.
