At least that’s what longtime songwriting cohort Johnny McDaid, whose also a member of Snow Patrol, does.

McDaid is taking credit for keeping Sheeran focused, though. “His attention span can be fairly low,” shared Sheeran’s writing partner. “One of the things I did to try and keep him in the room when I would be working on a track, I’d have like a suitcase full of legos I’d pull into the hotel room and say, ‘There you go. You build that.'”

“Shape of You,” which became the most-streamed song on Spotify ever this year, has been on the Billboard Hot 100 since it dropped in January, giving it the most weeks ever on the chart, and is closing in on a staggering 3 billion plays on YouTube. (Sheeran’s catalog has also been keyed more times than any other artist this year on the streaming platform.) But the song wasn’t originally intended for the Brit’s most recent album. As the clip recalls, Sheeran was instead considering it for “a female harmony group, or as a male-female duet, or maybe a song for Rihanna.”

And altogether, the cut was penned and produced in 90 minutes flat. As Mac says: “It was the best hour-and-a-half of my life.”
