Apple’s iTunes Web site has been updated with a placeholder page for the upcoming Pepsi and iTunes promotion, which will kick off Feb. 1 during the Super Bowl. The new Web page, which allows you to sign up to be notified when the promo launches, also reveals what appears to be the tagline for the promo: “More than pop.” The page reads: “Soul. Metal. Funk. Rock. Rap. Punk. More than pop. Jazz. Country. Blues. 100 million free songs. 1 in 3 wins.”
