Universal Music Group said it has acquired a stake in the operator of hip-hop/urban social networking website Loud.com (a.k.a. battlerap.com). The deal is part of the company's strategy to gain new sources of revenue and media outlets for its recording artists. The ad-supported site caters to hip-hop fans who can upload their own raps and compete for a record deal with SRC Records, a label distributed by Universal. The site also sells the song files for 99 cents each.
