American singer songwriter Bruno Mars has recorded songs for three studio albums, one collaborative album, one extended play (EP) and three soundtrack albums. He has also featured as a guest artist and provided background vocals to other songs. After an unsuccessful contract with Motown Records and a fruitless conversation with will.i.am's management, Mars signed with Atlantic Records in 2009. He came to prominence as a composer for other artists with Philip Lawrence and Ari Levine, who called themselves the Smeezingtons. They composed B.o.B's "Nothin' on You" (2009), and Travie McCoy's "Billionaire" (2010); Mars sang on their choruses.
