"Who Am I (Sim Simma)", or simply "Who Am I", is a reggae single released by dancehall artist Beenie Man in 1998.
The song is based on the "Playground" riddim (instrumental accompaniment), which was produced by Jeremy Harding.
I heard a knocking one morning...and couldn't believe when I saw Beenie Man sitting outside complaining about how long he had been banging down the door.
"[1] The track helped to introduce Beenie Man to the world as a new reggae star in the pages of Newsweek and other major media outlets.
He used a portion of this song in his reggae fusion single "Girls Dem Sugar" featuring Mýa which was released in 2000.
