iTunes U.S.

DOWNLOAD THIS: While the album side of the iTunes leaderboard is mostly notable for reflecting the tight race for next week's #1 between Kenny, Tony-Gaga and Babs, we do note the persistence of Pentatonix (whose new video has garnered nearly 600k views since debuting yesterday) and the presence of Meghan Trainor's EP in the Top 10. The latter's "All About That Bass" sits at #1 on the singles side, where the pithily titled, Isley-powered new Kendrick Lamar track and Tove Lo's addictive "Habits" have pushed their way into the rarefied terrain of Taylor, Ariana, Iggy and Nicki. Meanwhile, Jason Aldean's action on both sides is a harbinger of a big ol' 10/7 debut. (9/26p)
