Cover Songs?

We all love hearing different versions of songs, and even more so when they're executed with class and poise. In paticular, cover songs at times, can become more popular than the original. An example would be Van Halen's cover of "You Really Got Me" which had originally been written by The Kinks.
So, are there any cover songs that you like or dislike or that have become more popular than the original copy?

Yeap...sometimes is covers much better then originals...

I don't usually like cover songs, but I did like Johnny Cash's "Hurt," Jimi Hendrix's "All Along The Watch Tower" and Ryan Adams' "Wonderwall."

Hands down, the worst cover I have ever heard is this:

I'm seriously in love with . It's a cover of Kanye West's song.
I like the cover way better than original. I feel it's more serious and sad, which is fitting for the lyrics. The video clip is well done as well. I can't stand Kanye's version, but I can't stop listening to The Fray's version. @_@

August Burns Red's version of hit me baby one more time is amazing. x]

I used to spend a fair amount of my time scouring the internet for good covers.

Live lounge is what I found. It's basically this radio show in Britain where singers cover other people's songs. (I'm sure someone actually over there could explain it better/correct me) You can check some (if not all) the covers on YouTube.

Paramore - Use Somebody (Original Artist: Kings of Leon)
Adele - Make You Feel My Love (Bob Dylan)
Noisettes - When You Were Young (The Killers)
Amy Winehouse - Valerie (The Zutons)
John Legend - Ex-Factor (Lauryn Hill)
The Kooks - Violet Hill (Coldplay)
Panic! at the Disco - Valerie (The Zutons, again)

I'm probably forgetting a ton...
