The Chainsmokers‘ hit song “Closer” featuring Halsey has been sitting at No. 1 on the Billboard Hot 100 for the last five weeks.

According to Alex Pall and Drew Taggart, “Closer” was inspired by Blink-182’s 2004 hit “I Miss You” but the two songs sound nothing alike. Upon closer listen, it’s clear that “Closer” sounds like a hit song from Summer 2015: “679” by New Jersey rapper Fetty Wap.

The two melodies are extremely similar, the only difference seems to be that Fetty’s song is in D major and The Chainsmokers is in A-flat major. Are The Chainsmokers gonna have to cut a check for Paterson’s finest?
