Wow - this seems like its going to be a very unpredictable game. I'm already shocked at some of the votes.
As far as voting for two songs in a round, personally, I like the idea even though it's a little more difficult to keep track of the votes. It's different, but I think everyone will adjust after the first few rounds. To me, it's really not a good idea to change the rule now that we have started the game this way.
