File music0 came with Licar. I renamed it from music to music0 and the current
file named music contains some other music, from here:

Program mikmod can be used to convert a *.mod file into a *.wav file, then
program ffmpeg can be used to convert that *.wav file into another format:

ffmpeg -i *.wav -ar 8000 -ac 1 music.wav

Then the program available here can be used to convert file music.wav into the
format required by the game:

gcc convert.c -o convert -Wall -W

Programs mikmod and ffmpeg can be found on the internet and are free software.
Don't forget to first rename current file music to something else and:

./convert music.wav music

The new music should be heard when starting the game.
