Opinions on song remakes (covers)

I listen to a variety of music but my heart belongs to rock. I have heard many different remakes of songs over the years and have found some to be better than the original artist and some that are severly lacking.

Loved it when Limp Bizkit remade Faith by George Michaels. There rendition of The Who's Behind Blue Eyes mad for the movie Gothika was good too except I was disappointed that they left out the uptempo part. Of course you can find these songs on yahoo music or by doing a google search.

I got to thinking about this topic while listening to www.scrubradio.com (internet radio I enjoy hense my username). I heard a remake of Phil Collins's In The Air Tonight by a band called Callbox. The cut is live and has a brief part of the singer talking to the audience but the music starts shortly after. I brought it up for discussion here because it is probably unheard of in most parts of the world.

You can hear the song here http://www.scrubrecords.c... the remake in this case isn't as good as the original, I applaude the effort to convert the song into rock. Callbox's orignal tune Strange Days is my favorite from the band. The lead singer is an has been for years a roadie for the band Tesla and works at J-Street studios in Sacramento California.

Nancy Sinatra's song These Boots Are Made For Walking has been covered and remade by alot of different artists over the years but my all time favorite was when Dave Mustane of MegaDeth reproduced it with a metal twist.

My vote for worst remake is Evanescense doing Nirvana's Heart Shaped Box. Amy Lee has a beautiful voice in my opinion but she should have left this song alone.

So now its your turn. What did ya think of the above Phil Collins remake? What is your opinon on remakes in general? Do you have a favorite remake that you would like to add to the discussion. I'd be glad to listen to and discuss any of them.
