This is my favourite Michael Jackson song, although probably not for the obvious reason that the lyrics are very self-responsibility focused.
No, it’s because the first time I heard it was actually when watching one of those gratuitous American awards shows (the Grammys, it turns out) back in the days when we actually gave a toss about that type of show. At the time I thought the performance was excellent and I remember it to this day.
I do, of course, like the concept that the only person who can make a change is the man in the mirror. My politics are really centered around that sort of philospohy. Maybe that’s why this song resonated, even back then.
