Changing battle theme

I want to make a mini-mod for my own game, changing the soundtrack of the fight against Baltazar with a soundtrack found on youtube.

I'm a newbie at audio-editing, so hopefully some of you can give me some tips.


I guess it would be something like this:

- need to extract the file
- cut the file (so it loops at the correct time)
- convert the file to correct format (?)
- change file name for Balthazar's battle music

Could someone help me with this?

Note: I'm only doing this to mod my own game by making the battle music more epic.
