Why? Tyler's tweet, sent earlier this afternoon explains:
So in lieu of the long awaited collaboration that never was, Tyler released a remix of Zayn's "Pillowtalk" on Tuesday. To accompany the track, he uploaded a video of himself dancing to the song—which he notes was a necessity, because he "HAD NO ART TO GO ALONG WITH THIS." Check out very a yellow-clad Tyler, the Creator goofing off to the bubbly tune above.
Tyler's remix was apparently produced in February—six months after rumors of the monster-collab got the internet humming. You can listen to the song via Soundcloud below, if you're not one for Tyler's bedroom antics.
