I heard this song a few times played on radio stations in Canadian stores a few years ago.

The song was sung by a high-voiced singer; it was probably a woman, but could have been a very high-voiced man like Maroon 5 or Train.

From what I can guess, the song didn't have a lot of instrumentation; it was more like guitars playing while the drums occasionally interjected with a dramatic beat, but take that with a grain of salt because I barely heard the instrumentation. I do know that it was in a minor key.

This is the melody of the chorus: http://i.imgur.com/IiCJxVV.png Or, here is an audio version: https://soundcloud.com/partageons/fsongidenti
