Hip Hop artist 50 Cent released his new album, “Curtis,” on MySpace Friday (Sept. 7) — days before the hotly anticipated disc is set to drop in stores. Every track on the new album is being streamed on 50 Cent’s profile at www.myspace.com/50Cent, which means the MySpace online community and the artist’s more than 900,000 MySpace friends were some of the first members of the public to hear his third solo effort, MySpace said in a statement. Special guests and producers featured on the album, which will be available in stores Tuesday, include Dr. Dre and Justin Timberlake. MySpace TV will also premiere a series of five exclusive 10-minute video interviews with 50, titled, “50 minutes with 50.”
