XM and MySpace have launched an online search for unsigned hip-hop and R&B artists on a special section on MySpace called "Show Us What Ya Got!" Submitting a song gives entrants the opportunity to perform at The Mix Show Power Summit, and one grand prize winner will get a mix tape created with a high profile DJ, an on-air XM appearance and more.

All entries for the competition must be submitted between now and August 31, 2007. The entries will be reviewed by a panel of judges made up of music editors and industry artists who will select 5 finalists and post their entries on the XM MySpace community page for open voting.

Video blogs will be posted regularly, featuring advice and trends in the urban music industry from DJ Enuff, founder of Heavy Hitters DJs; Rene McLean, CEO of The Power Summit; and Bryan Leach, senior VP of Urban J Records and president of Polo Grounds Music. Video blogs with behind-the-scenes advice will also be available by on-air talent from XM's urban channels, including: Mz. Kitti, DJ "Funkregulata" Celo and DJ Furious Styles from RAW (ch 66); Lisa Lisa, Tiff Square, and Nina Nine from The City (ch 67).

Members from the MySpace community can view blogs and vote for their favorites among the top five finalists.

Three finalists will be selected for superstar treatment, including a free trip to The Power Summit, on October 24-27 in the Dominican Republic, to perform for an audience of the top record industry elite in the country. Past performers include Kanye West, Eminem, 50 Cent and Alicia Keys. Leo G, program director for XM's RAW channel, will be among the panel of on-site judges to watch the performances, provide on-the-spot commentary and award a grand prize finalist.

The live performance will be broadcast live on the XM MySpace community page reaching MySpacers around the globe.

The grand prize winning artist or group (who'll be selected by The Power Summit audience) and will receive:

• A mixtape created with a high profile DJ
• The opportunity to appear as the opening act on the MySpace Secret Show, a series of music performances only available to "friends" of the page.
• A local grassroots sniping promotional campaign
• All expense paid trip to be a guest on XM Radio in Washington, DC, and two weeks XM airplay
