As a featured artist in someone else’s song:
Trey Songz, “Bottom’s Up”
Kanye West, “Monster”
Ludacris, “My Chick Bad”
Drake, “Make Me Proud”
Britney Spears, “Till The World Ends (Remix)”
Big Sean “Dance (Ass) Remix”
David Guetta “Turn Me On”
Birdman “Y U Mad”
And the list can go on.
I am adding this new B.O.B. song to this list. The song, the beat, his verse, HER verse. Mama likes.
