Nine Inch Nails, "The Hand That Feeds" (DFA Remix)

DFA honcho James Murphy threatened to replace Trent with a soul diva and turn "Hand" into the gayest disco song ever. He fulfilled half the promise: Reznor’s vocals stayed, but DFA’s oscillating synth pans, handclaps, and wreck-room bass lines wipe NIN’s aggro sneer in favor of liquid-crystal debauchery and more cowbell. It’s downloadable as part of DFA in-house DJ Tim Sweeney’s two-hour NYU radio show Beats in Space, which also includes new tracks by the Juan MacLean and DFA remixes of Soulwax and Jon Spencer.

DJ Riko featuring Katie Enlow, "P-Funk Is Playing at My House"

Local girl Katie Enlow, sister of DJ Luke Enlow (a/k/a Lenlow of Boston’s "Mash Ave." nights), may be the first singer to make her name by singing exclusively on mash-ups. And not just her brother’s: she’s become the go-to girl for English mutant-pop DJs from Essexboy to cry.on.my.console. On this remix of LCD Soundsystem’s "Daft Punk Is Playing at My House," Katie recuts James Murphy’s vocals while Riko hijacks LCDS’s robot house party with a crate of Parliament/Funkadelic vinyl.

Kelly Osbourne, "One Word (Favela Funk remix)" (iTunes)

The title of this remix has less to do with its relationship to Brazilian ghetto music than with Kelly’s desire to court M.I.A.’s early-adopting fan base. But if it’s several degrees more pristine than "Bucky Done Gone," it also comes closer to the bleak, existential throb of Mantronix than anything on Kelly’s forthcoming electro-pop album Sleeping in the Nothing (Sanctuary).

Charlotte Church, "Crazy Chick" (www.charlottechurch.com)

Nobody knows why the caged bird sings better than Church, who rose to childhood fame via precociously pious renditions of classical crossover hits. Her debut as a soul diva isn’t due until July (though the video and the ringtone are for sale at her Web site), but in a sign of good things to come, she’s already been slagged by Kelly Osbourne. Backed by muggy organ stabs, "Chick" takes Church to, well, church, where she explores a lusty lower register and unleashes enough pent-up libidinal energy to have powered all four Pointer Sisters in their prime. "I just can’t help myself, I need professional help," she wails: is this what it sounds like when doves cry?

Head Wound City, "Prick Class" (31G)

You have to wonder what that new Yeah Yeah Yeahs record is gonna sound like: first Karen O sits in with Some Girls, and now Nick Zinner forms a self-proclaimed "skate-thrash" supergroup with the Locust’s Justin Pearson and Gabe Serbian as well as the Blood Brothers’ Jordan Blilie and Cody Votolato. This advance teaser is a 90-second air-raid drill, with dub-plate echoes and screeching guitars that circle ominously, like a wobbly merry-go-round on its last legs.
