Ariana Grande’s “thank u, next” is one of 2018’s biggest hits, but listeners on social media have noticed that its melody is eerily similar to the theme from Merry Christmas, Mr. Lawrence composed by Japanese musician Ryuichi Sakamoto.

“thank u, next” is produced by regular Grande collaborators TBHits and Social House, and does not contain any samples, making the similarity likely a coincidence. Sakamoto hasn’t commented on the similarities, but has been spotted listening to the track on Spotify. Sakamoto is best known for his experimental electronic music—both solo and with Yellow Magic Orchestra—as well as for composing the music in films like The Revenant. He won a Best Original Score Oscar in 1987 for his work on The Last Emperor.

Sakamoto released a version of “Merry Christmas, Mr. Lawrence” on his album 1996. His last album was 2017’s async.

Though best known for his music, Sakamoto actually had an acting role in Merry Christmas, starring opposite David Bowie and Tom Conti.

Writer and musician Noah Yoo of CAFUNÉ combined the two tracks, slowing down an acapella of “thank u, next” and laying it over the theme’s contemplative piano and strings.

Though Grande’s composition is an original, plenty of artists have sampled Sakamoto’s other work, including Danny Brown on “Greatest Rapper Ever,” Freddie Gibbs on “Walk in Wit the M.O.,” and Jay Electronica on “better in tune w the infinite.”

“thank u, next” had the second biggest debut in Genius history, reaching a million pageviews in 13 hours. It currently sits atop the Billboard Hot 100, and its video set a YouTube record for views in a 24-hour span.

Genius broke down the “thank u, next” video with director Hannah Lux Davis in an episode of Framework.
