It's airing on the radio all the time, here in France at least.
Repetitive old-school electric guitar riff, with house-ish danceable beat (maybe a rock song remix).
Male voice, distorted, sullen, kinda makes me think of a prison song.
Didn't understand the vocals at all, thought he said "the hanging tree" somewhere in the chorus but lyrics search found smth totally different...

Any idea?
