How to choose the background music played?

I was testing a map and the race that I used is based on NE.

However, 3 minutes into the game I was crashed onto the desktop and it said the NightElf1.mp3 file is corrupted.

I've no idea what caused it so I want to change the music. Any idea?

It might simply mean that your installation of Warcraft 3 is corrupted. Are you willing to consider reinstalling it to try to fix your problem?

I don't mind spending time re-installing if it'd help.

Thanx for the solution ^^
