British singer-songwriter Ed Sheeran has revealed that while he was writing his collaboration with Taylor Swift, 'Everything Has Changed', they both disagreed on one of the song's chords and had an argument about it. 

During a new interview with BBC Radio 1's Zane Lowe, the 'Lego House' hitmaker explained that they kept butting heads over one part of the track in particular, so he eventually forced his ideas on her and they finished the offering:

"I went to her house, she cooked an apple pie... She did. She cooks really good sh*t man. And then she gets up, she has a little Taylor guitar, and she got it out and she's like, 'I've had this idea for this song and it goes...' (Ed does impression, humming the tune and singing the chorus),"

"And it kind of had... She pretty much had the verse, bridge and chorus done but we argued about that one chord (plays it). She didn't like that and I kind of forced it upon her!"
