Charli XCX recently told The FADER that she wants to make "the best pop album of 2017." So it makes sense that she'd appear on former Vampire Weekend member Rostam's remix of Jim-E-Stack's "Deadstream," a standout electro-pop single from this year which also became a very poetic Vine meme. The remix premiered this afternoon on Beats 1. Its new additions transform the song from a hidden gem into an all-out one, thanks to a duet between Rostam's Prismized vocals and XCX's bubbly and forlorn melodies. Listen below.
