In my opinion the song that has aged the best by Bruno Mars is probably Grenade. This song was released in 2010. There were several people who wrote the song. They were Bruno Mars, Phillip Lawrence and Ari Levine. Bruno Mars has stated that the song is one of his favorites that he has written and sung. The song is considered to be a mix between pop and R & B.
There are a few musical instruments that can be heard in the song including drums, a keyboard and a piano. I believe the reason this song has aged the best is because you still hear it and I think people still think it is a new song. It is hard to believe that it was written a long time ago.
