Open your game's config.ini file using wordpad. Look for; "[game]" and in the section under that; "Intro=1". Change it to read "Intro=0". Save the change, close the file and start the game. The intro track should not play now.
You do not say which version of the game you are using- if you install one of the mod packs, you will not need to CD to run the game.
If you prefer to use a stock version of the game, do a search for "No-CD Crack".
