Bruno Mars isn't creative and is just an entertainer?
Some of you have lost your minds or don't know what you're talking about.
Dude started off writing and producing songs for other artists, including some of their biggest hits.
List of songs written by Bruno Mars - Wikipedia, the free encyclopedia
Dude just co-wrote (maybe even the whole thing) “All I Ask” by Adele on her new album, which is one of the best songs on there. Dude has just reached “in demand” status from here on out as a songwriter.
One of the few pop stars today who doesn't go to Max Martin or Dr. Luke to write their hits (The Weeknd). Almost all of his success is done with him and his band. Probably most song-making gifted big name artist next to Lady Gaga.
