YouTube has revealed a new music contest dubbed YouTube OntheRise Rap Edition, which aims to identify the best unsigned hip-hop artists in the United States.

YouTube has tapped hip-hop artists 50 Cent, Common and Polow da Don to judge the videos. Finalists will then be presented to the YouTube community for a final judgment. Users will be able to submit original music videos from Aug. 10 through Aug. 17. The final winner will be revealed Sept. 7.

The winner will be given a trip to New York to record a track for G-Unit/Interscope Records, a $10,000 gift certificate to Guitar Center and a feature spot on YouTube's homepage.
