Many people only know him because of his great ballads. Not so many people know him for being such a good entertainer and his sexy dance moves. He did awesome.
Honestly, as the Superbowl, doing sad/sappy love songs isn't something people want to hear, they wanna be HYPED. Three of Bruno's biggest songs are sad ballads
-When I Was Your Man
-Grenade
-It Will Rain
There's a reason why Beyoncé didn't perform any of her break-up songs (Specifically Irreplaceable)
Bruno.
