It doesn't need to be updated. Some stuff is just so iconic you leave it alone.It can be updated for modern ears.
When that was recorded it was done on inferior hardware.
Now they can clean up the music to let you hear it better.
Probably hear the strings and the instruments better.
Of course if they do try to reuse that music they are going to try to see if they can give it a modern mix it for use in other places.
And that music has a dramatic feel, so them trying to force that feeling on a regular season game in today's game is not going to work. We all know it's not that important.
It's kinda like how they fukked this song up. Ends up sounding like a cheap imitation of the original.
