Don't

This angsty breakup tune is about an ex, and Sheeran doesn't hold back with how he feels about her. "The story in 'Don't' is 100 percent true," Sheeran told Billboard magazine. "I could have gotten nastier - there was more s--t that I didn't put in. I was seeing someone for a bit of time, and then they ended up physically involved with one of my friends in the same hotel that we were staying in, while I was downstairs. And I feel like: Treat people how you want to be treated."

Speaking with MTV News, Sheeran refused to name the mystery person that the song is directed at, but is sure they will know who they are. "I've always been the sweet, innocent, 'Oh my God, he's English!' kind of thing, so having a bit of bite," he told MTV News, "I don't know how that's going to go down, but based on the reaction of people that have heard it, I think it will go down just fine."

Fans have speculated that the song could be about Ellie Goulding. Sheeran dated the "Burn" singer during the summer of 2013. She was rumored to have been seen kissing One Direction's Niall Horan at the V Festival around the same time. Some of the speculation that Goulding is the subject of the song was because of the lyrics, "We make money the same way. Four cities, two planes the same day," and "You were looking for a lover to burn." Not only does Sheeran allude to the pair having the same career, but he also includes the word "burn," the title of Goulding's hit single. Goulding apparently responded with a line in her song "On My Mind" ("You wanted my heart but I just liked your tattoos"), but she denied ever being involved with Sheeran.
