In fact, Sheeran revealed two interesting nuggets about the song. Attention has been paid to his song "Don't," which may or may not be an Ellie Goulding diss track, but he said "Sing" deserves a similar look: "'Sing' is about a very, very well-known person," he said. "No one knows that, so no one's being like, 'Who's it about?'" Oh, and there's another thing: the song apparently has a Psy remix.

In the story, Times writer Jon Caramanica points out that at one point, Sheeran pulled out his phone and played a small bit of a "Sing" remix that the K-pop superstar had recorded.

Nothing else is mentioned about the remix - whether or not it'll see the light of day, for instance - but it isn't a farfetched pairing. In recent interviews, Sheeran said the puppet-themed video for "Sing," which features a boozy night on the town, was actually inspired by a night of drinking and singing karaoke with Psy.
