New Britney Spears and Middle Brother

Singles, file, for the week of Jan. 11: New Britney Spears and Middle Brother

Singles File A weekly playlist for the listener with a one-track mind

Britney Spears: "Hold It Against Me" Is it a Gaga slayer? Probably not, but the first track from Spears's upcoming don't-call-it-a-comeback disc mixes the best of Gaga, RiRi and mid-'00s electro-inspired Europop.

Middle Brother: "Me Me Me" The leaders of Delta Spirit, Dawes and Deer Tick form a blog-baiting supertrio with an unexpectedly raucous debut single that's equal parts early Guided by Voices and vintage Big Star.

Curren$y featuring Sir Michael Rocks and Tabi Bonney: "Fly Out (Part Tres)" The ever-prolific Spitta enlists Bonney and half of the Cool Kids for this super-funky, Michael Jordan-dissing new track.

Second City Rhythm: "You Got Me" Chicago DJ Adulture and British remixer Ghosts of Venice unite for this disco house scorcher, the maiden single from their upcoming EP.

Villagers: "Old Man" (Neil Young cover) Ireland's greatest one-man band essays an uncannily good, essentially faithful cover of Young's "Harvest" classic for Mojo magazine's upcoming tribute disc, "Harvest Revisited."
