 [hide*1 Composition


The majority of the song is upbeat and Electro house style until vocals from Harris come in. When the vocals do come in, the background tune is just a piano being played until Calvin Harris sings "Our hearts will never be the same again". When this happens, the tune turns upbeat again.

Swedish DJ Alesso has criticized the song for being a copy of his own unreleased track "Clash".
