Several days ago, Kanye West made an appearance at the iHeartMedia Music Summit in California, where he played a snippet of an acoustic song featuring Rihanna. That song has now been released, and it’s called “FourFiveSeconds”. The singer uploaded the track – which. as Stereogum points out, also features Ty Dolla $ign and the Dirty Projectors’ Dave Longsreth in addition to West and Paul McCartney – to her website on Saturday evening along with the artwork shown above; it’s also available now on iTunes, but you can listen and download it free below!
