Duke 3D's soundtrack was not exclusively the work of Bobby Prince; Lee Jackson, Apogee's go-to music guy, also did some of the tracks, including the title theme, Grabbag.
Prince used not only his MIDI skills but also his experience as a lawyer to ensure his 'inspired' derivatives were as close as legally possible to the originals. The relationship between individual tracks is often very clear and sometimes even hinted in the metadata of the source files.
