I got 3 that comes to mind.....

Wish you where here - Pink Floyd
The Dance - Garth Brooks
Hurt - Johnny Cash

Watched a documentry on Johnny Cash one day... I was like wow that dude has been through the ringer. Then 2 days later I watched the video of the song and it sent chills up my spine. That was (in my oppinion) one of the best remakes I ever heard.
