It doesn't always work out, but when an artists covers another another artists' song and it does work out, it's pretty cool.

Thomas Rhett is a country music singer who has taken a liking to Bruno Mars' "When I Was Your Man". When somebody like "Mr. Do-it-all" Justin Timberlake covers a the legendary Garth Brooks' "Friends in Low Places", you can bet it going to be pretty great.

What happens when the roles reverse and country goes pop? Thomas Rhett answers the bell and does a great cover Mars' song.
