What cover songs were better than the original versions?

[CFH]

I don't actually know that many covers. So it is good to get a list to judge from. I mean, it was just like 2 years ago I was listening to stuff like Green Day thinking it was awesome, and now I hate them...so...

Would Mr. Breeze by Lynard Shynard be considered a cover, seeing as J.J. Cale wrote it, or? And how about SRV stuff? I mean, most of his songs someone else did first.

I would say it's considered a cover if the artist was not the first to perform it . IE If J.J. Cale had played/published Mr. Breeze, then it's a cover.
