Patrick Stump goes soul. (Josh Sisk/For The Washington Post)

Danny Brown: “Brown Eyes”

The Fool’s Gold MC samples Brian Eno (why don’t more rappers do this?) on his typically frenetic new track.

Apparat: “Song of Los”

The Berlin-based producer/artist offers up dreamy electro (and robots!) on this standout cut from his phenomenal new disc, “The Devil’s Walk.”

Patrick Stump: “Allie”

Former Fall Out Boy frontman mines an emo soul groove on this minimally instrumented new solo track.

Iggy Azalea: “D.R.U.G.S.”

“I curse like a sailor,” the spanking new Aussie rapper warns on her raw, triple time, definitely NSFW new track, and boy, she is not kidding.

Void: “Please Give Us a Chance” (reissue)

The Columbia, Md.-based hardcore pioneers will get the demos-and-rarities collection they deserve when Dischord releases “Sessions 1981-83” this month. On this short, perfect track, they somehow insult themselves and explain their awesomeness all at the same time.
