iTunes charts

DOWNLOAD THIS: The stars of several genres are out this morning. Arcade Fire, proudly representing indie rock, is perched atop the album chart. Teenpop heroes 1D are growing up in public, zipping to #1 on the singles chart with a new offering while the quintet’s upcoming album sits at #3 as a pre-order. Rap god Eminem is setting up Marshall Mathers 2, just made available as a pre-order seven days before release, via a Rihanna reunion single (hear it below). Pop divas Katy Perry (hours away from being crowned on the HITS album chart) and Lady Gaga, with a brand new single of her own, are booked for extended stays on both big boards. Newly minted star Lorde is holding strong amid this heavy-artillery barrage. And Kelly Clarkson makes a fetching Santa. Deck the halls, y’all. (10/29a)
