So, on a whim I went to my audioscrobbler page and found that it'd turned into my Last.fm page. It now has nifty features like playing music from your own collection as a streaming "radio" station (though you can skip songs you don't like), or you can play radio from friends or neighbors. OK, some of these options are only available for paid members, but listening to neighbor radio, or one of the collection radio stations, is free. I'm finding it pretty cool, mostly because now I don't need to worry about bringing my music from home into work.
Also, are any of you already there? I'm "gwenix" as usual, and I apparently have no friends. It is sad.
