[Did a forum search but didnt come up with anything similar, so soudns like this is something that hasn't been suggested before]
I think that when in a multiplayer game, you fail, you should be able to (while still in that game) spectate any of the other players (maybe only players that haven't failed yet) So instead of the usual having to quit multiplyer, then spectate someone, you could do so before the song ends in your current multiplayer game.
This would be great as half of the time you can't be arsed to carry on playing when you've failed and spectating the leading player would be a lot better :l
