The British-born Lawson has opened for Sheeran on tour and "Wasn't" was the song that won the "Thinking Out Loud
" star over. "I cried, I cried the sixth time I heard the song," Sheeran said of his reaction to the track. "I see it as the musical version of The Notebook
. For me, that's what it is. Anytime a dude has seen The Notebook
, they'll never tell you that they've seen it because then you're like 'Did you watch the end?' I found the song like that because any dude that has listened to it, you're like 'What did you think of the end?'"
