If Lady Gaga coming back to town wasn't pop-tastic enough for you today, then consider this: The Black Eyes Peas just announced that its "E.N.D. World Tour" will be stopping at the Scottrade Center on August 14. Tickets are on sale Saturday, March 20, at noon. The group's current radio-dominating hit is "Imma Be Rocking That Body." Just try to get it out of your head once you hear it. I dare you. This is A to Z's current guilty pleasure tune.
