ON THE DOWNLOAD: It's iTunes domination for Robin Thicke this week. The Star Trak/Interscope star's single "Blurred Lines" has ruled the singles chart since forever, and now his newly released full-length, Blurred Lines, is the #1 album. He's followed by Prospect Park's heavy rockers Five Finger Death Punch; indeed, two versions of the rock band's album occupy the Top 5, with the "deluxe" edition at #2. Syco/Columbia's Emblem3 and the Backstreet Boys (K-Bahn), for their part, demonstrate the power of both new and veteran boy-band Pop. Rapper Tech N9ne's guest-studded new one on Strange (featuring Kendrick Lamar, Cee Lo and System of a Down frontman Serj Tankian, among many others) blasted its way to #5. Pre-orders on Capitol Nashville's Luke Bryan have helped him amble into the Top 10. Hollywood's Selena Gomez (#1 on this week's HITS Album Chart), fellow Disney attraction Teen Beach and Roc-a-Fella/Roc Nation's Jay Z, meanwhile, stay in the fray despite all the new product. On the singles side, things look a lot more familiar, though it's worth noting the tenacity of Labrinth f/Emeli Sande (RCA) and the Pitch Perfect hit "Cups" as performed by actress Anna Kendrick (UMe).
