So which are you suggesting - 1983 Michael Jackson ripped off 2012 Bruno Mars or 2012 Bruno Mars ripped off unreleased 1983 Michael Jackson?
I'm just being an asshole; I can hear it.
Lol, Bruno got in his time machine, traveled back to 1983, held MJ at gunpoint and told him if he ever released the song he would make horrible allegations against him. He then traveled back to 2012, got on his hover board and went to the studio to record his treasure of a song. This is the reason why we are only now hearing this version. Coinidentally, I'm driving 88 mph while listening to this MJ&JT right now....should I slow down?
