Liam and I see who knows their lyrics best, and yes – Liam is only 4! My friends Brittany and Derick have the cutest, craziest kid, and all day long he loves to listen to music. So I figured I’d put this 4-year-old to the test to see if he knows lyrics better than someone my age.

Watch and see, I think you may be surprised at who wins, and by how much.
