French musicdisc from 1989 featuring the game music of Jonathan Dunn.
With the exception of the last track each track is given 90 seconds of playing time giving a total of 16 minutes of music.
Switching between the tracks is virtually instantaneous so it looks like all the tracks have been merged to form one large data file.
The demo structure appears to consist of this - BASIC loader - screen file - m/c file (player) - music data file - scroll text file (data?).
