Singer Chris Brown is ticked off that a song from his next CD has already been leaked to the Internet. Fans are already getting a taste of the artist's "Electric Guitar," a tune featuring Rihanna that is supposed to be from the singer's third album, due next year. "I'm mad that it's leaked," the 19-year-old Brown told The Associated Press. "The record's not finished. It's supposed to be me and Rihanna's duet."
