Has anyone used
LaunchCast Radio? It's built into Yahoo messenger.
Basically you can create a customized radio station by telling it which genre's, songs, artists you like by rating them 0*'s to 4*'s. Then it will randomly play those songs / artists as well as other stuff that's related to it (either because its by the same artist, in the same genre, or other people that like something you picked also liked this new song). And if it plays something you don't like -- you mark it with a 0 (aka "never play this again").
So --- I think its pretty good, and am actually thinking I might pay the $3.00/month to get LaunchCast Plus -- which also allows you to create "moods" -- like all your favorite oldies stuff, or jazz, or angry hard rock. And you can pick "influencers" so if a friend of yours has cool music taste -- you can have their likes influence what you listen to.
Anyway. Has anyone else used it? liked it? opinions? or found something else you liked better?
