It Ain't Me is Gomez's first release since the cancellation of her Revival Tour last year and since checking into rehab for assistance with anxiety and depression caused by lupus.
Gomez has teamed up with Norwegian DJ Kygo, best known for his remix of Ed Sheeran's I See Fire, and his hit single Firestone.
The new track sounds almost acoustic in the verses but quickly merges back into familiar EDM-pop territory with the stuttering chorus. The song bitterly details what Gomez used to do to be a doting girlfriend and why she's no longer going to be there for her trashy ex. Hmmm....
