"Pray," the only new track on Justin Bieber's forthcoming acoustic effort "My Worlds Acoustic," has hit the web two weeks before the disc's November 26 release. Earlier this week, the pop star announced the mid-tempo single and unveiled the artwork of "Acoustic," which will include stripped-down takes on his hits "Baby," "One Time" and "U Smile." Unlike the strictly acoustic tracks on the album, "Pray" uses a string section, synthesizers and congas as Bieber offers an inspirational outlook on the future. "I know there's sunshine beyond that rain, I know there's good times beyond that pain/Heaven, tell me I can make a change," Bieber sings. In other Bieber news, the singer has announced the creation of www.Bieberpix.com, a forum for photographer Robert Caplin -- who worked on the art for Bieber's memoir, "First Step 2 Forever: My Story" -- to post exclusive pictures of Bieber. Prints of the photos are being sold on the site, with proceeds going to an unnamed charity. " is gonna be posting never before seen pics every week to help others," Bieber wrote on his Twitter account yesterday. (Editing by Zorianna Kit)
