I have heard "Nothing Else Matters" by Metallica several times. And yes, it is one of my favourite songs. But then, there is something about this version of " Nothing Else Matters" by Chris Isaac and Metallica. I have been listening to it continuously for some days now and I am still not bored. And when I try to switch to some other song, I feel that it is not upto the mark and so I switch back to this version of "Nothing Else Matters" again.:-)))
