Because they are alike in one thing, the chord progression.
"Don't you want me like I want you baby" and "I'm not saying we ain't got problems" is the same melody, just different tempo.
It's the same as in Coldplay's Viva La Diva, Pitbull's Feel This Moment, One Direction's Night Changes, Troye Sivan's One Of Your Girls, among probably many many more. It's very popular.
I was trying hard to remember which song sounds like โStart a Warโ like that tune was very familiar to meโฆ All Iโve seen on twitter was the night changes and feel this moment, but I donโt even think they sound alike.
And I finally found the answer, it is One of Your Girl. So thanks for this ๐คฃ
