The Amiga musics I prefer are :
1. Some musics from the game "Rody & Mastico", the best balanced compositions I have heard on the Amiga. I have never identified their composer.
2. Jean Baudlot's soundtracks for "Les Voyageurs du Temps" ("Future Wars" in English) and "Operation Stealth", featuring a fairly unique expressionist approach of music, that suits the module format very well.
3. "Project One" by Karsten Obarski : while most Amiga musics from demos or the 90's tend to cover up the perfectible quality of the 8-bit sounds instead of exploiting it, "Project One" is in my opinion as outstanding today as it seemed insignificant in the Amiga's glorious time.
