Singles from Rick Ross, Rye Rye, Theo Martins, Mr. Oizo and Gaspard Augé, R.E.M.

Rick Ross featuring Drake and Chrisette Michele: "Aston Martin Music (Official Extended Mix)"

The latest from "Teflon Don" is a drowsy, summery stunner complete with a Courtney Love shout-out.

Rye Rye featuring Nguzunguzu: "B.A. Mix"

"The A-Team" may not have been a cinematic worldbeater, but it birthed a bumper crop of excellent title theme remixes, including this lively one by perpetual star-in-waiting Rye Rye.

Theo Martins: "20,000 Leagues (The Feather)"

The Rhode Island rapper waxes nostalgic over a sample of Little Dragon's "Feather."

Mr. Oizo and Gaspard Augé: "Tricycle Express"

First, French house music titan Quentin Dupieux, a.k.a. Mr. Oizo, made a film, "Rubber," about a telepathic, serial-killing tire named Robert. (Don't laugh; it went to Cannes.) Then, Dupieux enlisted Justice's Augé to assist with the film's surpassingly good, surprisingly un-sinister score, excerpted here.

R.E.M.: "Throw Those Trolls Away"

Nostalgic for the days when R.E.M. was one of the world's best bands, and "trolls" didn't refer to mean people on the Internet, mostly because we didn't know there was an Internet? This demo, part of a bumper crop of rarities packaged with the new "Fables of the Reconstruction" reissue, will take you back.
