"I Was Made For Loving You (feat. Ed Sheeran)" by Tori Kelly
Yes, another one that features Sheeran's voice, but the backstory is pretty charming. Apparently, Sheeran wishes he had kept the song for himself. He told the story on Fresh 102.7 NY: "I remember writing that with Tori and saying before, 'Whatever we write, definitely for your album, don't worry about it,' and remember halfway through being like 'Agh, God I wish I was keeping this.' It is a really beautiful song and it's turned out so, so well. But that's one song that I wish I'd kept."
