You've just said what I've been thinking all these years. Except the video. I think that might be why people praised it. They knew he didn't have long to live and the video is pretty heartbreaking when you think he might have chose the song because he was bitter about losing everything he ever worked for.
IMHO, the cover sucked but I do think it was from the heart.
It's crap like this that's the reason why I started looking for alternatives like Lemmy. Reddit is getting a little too big for their britches.
