Sometimes they play a back story so you can root for the contestant. These two wanted to know nothing about the singers.
The show is worth watching if nothing else because of the after interviews with Cee Lo where last year he held a cat in his lap like some kind of villain and this year talks to a bird. Awesome.
This guy is my favorite. He likes like a Muppet and sounds like Bill Withers. This fills my heart with pure joy.
