Each time a player finishes a set of twelve questions, you hear a mad piece of music. Maybe the music is too mad to listen to, maybe you find the music not mad enough. In both cases you can change some or all music files.
Suppose: you want to change music #1, #8 and #11. What to do?
1. Make music of your own. All is possible: rain; a hail storm; a barking dog, etc.
2. Save your sounds/music in mp3 format:
etc, etc. (The letters muz are the first three letters of the Dutch word "muziek.")

3. Copy your music to this map: Android/data/ on your tablet.
From then on, ATLAS10 will use your music.
