DJ Chall, I'm looking at you!
Ok... so you start the game by picking an artist (band or singer). Then everyone writes down ten artists they think will come up when you listen to that artist's station on Pandora. Then, you listen to ten songs on Pandora. The person with the most hits wins that round and picks the next artist.
I'm thinking of calling it "Pandorette", but I'm open to ideas.
