I was using Slacker last night and it was great, hadn't tried it today, but just did when I read the posts above and lo and behold, it's freaking broken
. If you the grooveshark website, you can make a playlist to use with nanogroove, but I'll also warn you, there have been issues with nanogroove although they do put out quick updates. One tried and true that has worked well was select radio and it has most of the local radio stations for me around here (although another poster was mentioning issues he's having with it today). I'm going to check out thestreamcenter later as that sounds promising too.
