Then you get him covering "Hurt"[1] from NIN and Trent Reznor says "that song isn't mine anymore" [2].

That was an amazing cover, I like both artists but Johnny Cash just blew that out of the park. Combined with his death just a few years later too, man.

"Personal Jesus" by Depeche Mode was also a excellent example.
