I don't know the music or the show that well... but most people, as far as I can tell, want something interesting if you are going to lip synch/dance. Make it really interesting, different style of dancing, something totally unexpected and/or really good. It's something that they see a lot of, so the lip-synch dance thing gets really old quickly, unless there's something to spice it up. Also, cut the song down to about a minute - no one needs to be lipsynching for longer than that.
