The No. 1 album on iTunes right now–ahead of High School Musical 3, pre-orders for the David Cook album, and last week’s Billboard 200 chart-topper Paper Trail–is Adele’s 19, which no doubt got a boost after the British chanteuse was on this weekend’s Saturday Night Live, the show’s highest-rated episode in 14 years thanks to cameos by Sarah Palin and Mark Wahlberg. Hey, maybe as a thank you, Adele will let Palin use one of her songs on the campaign trail! OK probably not. [iTunes]
