Well, I used to be a paid Launchcast subscriber before it was flushed by Yahoo. That about sums up the experience for paid subscribers. Unpaid subscribers had limited skips and a few commercials now and again.
I do like Pandora, but I greatly preferred my Launchcast stations because you could rate genres 1 to 100, artists 1 to 100, albums 1 to 100, and songs 1 to 100. Then you could apply moods to your stations. It was VERY granular and my station only played the songs I really really liked or wanted to listen to at that time. It was pretty amazing.
