I find the mystery part it much more interesting than the Voice or American Idol. It's about the only tv show my 14 yr old boys watch right now, solely because of mystery and fun nature of it. It's not like they would know any of the singers.
I think the judges are also prompted to throw out crazy suggestions they know are not right (somebody said Obama for one of the singers) but I'll give Jenny McCarthy credit for calling the loser as either Cheech or Chong. I was personally guessing Tony Hawk for him.
