On the inspiration behind the song, Grennan stated: Recently I received the tragic news of a friend’s mum’s passing.

It hit me hard watching him comprehend what had happened, trying to compute the madness and sadness of his new world now that his mum whom he loved so dearly had passed.

It was cathartic on many levels, thoughts of loss and heartbreak, dealing with the grief of death, or the breakdown of a relationship or friendship.

[2]Liv Rose of Gig Goer described "Don't Break the Heart" as "a euphoric track inspired by personal loss and grief.

As gentle, acoustic guitars build to powerful percussion", featuring as "tackles complex human emotions in a remarkably uplifting way".
