Well, we don't really know what killed him--yet. There is the official version, which could well be accurate, but there may be more to the facts than that. In the event, a most untimely passing. I wasn't a fan (my sister was--women seemed to really like Wham! and Michael in particular) but he did write some hook-laden hits, He also had artistic control of his music at a time when many plying the same turf did not, which is no small feat.
RIP
