Christina Aguilera has one, Blake Shelton has two, Adam Levine has two and CeeLo Green has three. The remaining eight singers on The Voice sang Monday night to avoid another elimination on Tuesday. But before the contestants were on, it was time for a coach to premiere a song. This time, it wasn't Christina; it was Adam Levine, singing the chorus for rapper 50 Cent's My Life. The best part of the song? Seeing Blake bobbing his head to the song, which had several bleeped words. Then, the final eight were on.
