Gnarls Barkley’s The Odd Couple, which had its physical release date bumped up from April 8 to “sometime this week,” has appeared on the iTunes Music Store, and it’s already No. 2 on the store’s album chart. Holding it back from the top spot–and bringing up its rear on the chart–are two editions of the new album by Danity Kane. People really care about Danity Kane beyond wondering whether that one member was sleeping with Diddy? Huh. I guess nothing really beats being on TV as far as exposure to the actually-buying-records public goes. [iTunes / Earlier]
