have you heard of turntable.fm? My husband told me about it and I love it! This is a screen shot of my favorite room. I am in there somewhere
You choose an avatar and pick a room with music you like and go there. When there is a free DJ spot, you head on up and play a tune. People either think it is "awesome" or "lame". For every person who likes it, you get a point. More points, different avatars. People can "fan" you and you can have favorite rooms. This makes it easier to find people you are a fan of when you are looking for a room to enter. You can create a room, but I haven't tried that yet. You can tweet or FB that you are in a room and it tells what room you are in and what song is playing. I like to tweet when I am playing something really cheesy.
If you try it, look me for, CucsMom!
