When "Only One," the Kanye West song featuring Paul McCartney on keyboards, was released, West's reps promised that more collaborations between the two were forthcoming. Sure enough, Saturday saw the release of a new single from Rihanna featuring both West and McCartney. The song, "FourFiveSeconds," is an acoustic ballad with Rihanna taking lead while West chimes in on verses and McCartney again handling keyboards. Despite the song's spare sound, numerous other musicians are credited with work on the single—including Dave Longstreth of the Dirty Projectors. Reportedly, the song will appear on forthcoming albums by both Rihanna and West. (Stereogum)

West first previewed the song during a Thursday speech at the iHeartMusic Media Summit in Burbank, California. During that speech, West revealed that he asked McCartney—in, um, explicit terms—what sex was like back in the 60s. (Rolling Stone)
