My favourite track of all time by any band is Nothing else matters by Metallica, I recently found the YouTube video where they are performing live with the San Fransico Symphony Orchestra and did Nothing else matters.

I was wondering if it was a track that they ever released on an album or perhaps as an additional track on another single.

Ive tried a search of the internet to buy and download it in Mp3 but cannot find it.

Has anybody got this track or know where to find it???

Thanks in advance to anyone who can help.
