Bruno Mars is the most-listened to artist in the world on Spotify. He's won 16 Grammys. In case you thought there were no battles left for him to win, this week he unlocked another achievement.

There are two clear frontrunners in this year's best original song race, either of which would be a worthy Oscar winner.

After two weeks at No. 2, IVE's "BANG BANG" moves up one spot to take over as the new No. 1 song. Congratulations to IVE!
