Bruno Mars ($150 million)
Even though Bruno Mars is an extremely talented musician and recognizable voice on his own, it wasn’t until he collaborated on Flo Rida’s 2009 Billboard hit “Right Round” that he got some global recognition. Since then, he has had several songs reach the Billboard top 10. It wasn’t until he released 24K Magic in 2012 that he started really showing up on the charts. 24K Magic swept every category it was nominated for at the Grammys and was awarded Album of the Year in 2012 over Kendrick Lamar who was a huge competitor.
