Adele wrote “Send My Love To Your New Lover” in collaboration with Max Martin and Shellback for her third album 25. Adele played guitar on the record, and it was this riff that began the song. She told the New York Times I’ve had that guitar bass line since I was, like, 15. I used to cover Wonderful World’ doing that riff. It sings over it really well. With [the producers] Max Martin and Shellback, we knocked that out in a day. This is a more upbeat, straight-pop record for Adele, which makes sense considering the super producers behind the sound. Prior to this record, however, Adele hadn’t heard of Max Martin or Shellback. It was listening to Taylor Swift with songwriter Ryan Tedder that led her to discover their prominence in the pop landscape. This song was originally titled “We Ain’t Kids No More,” but at the last minute, at the encouragement of her manager, Adele decided to change it. She told Rolling Stone Otherwise, you might as well just call the fucking album Old. Given that a lot of the songs on this album are about nostalgia for childhood and the past. The song is directed toward the guy Adele dated between the subject of much of 21, and her husband, Simon Konecki. He previously inspired one other track, “One and Only”.
