We assume that the Spear of Destiny fanfares were also composed by Bobby Prince (or Tom Hall with John Romero, because they were responsible for voice actions and some other sounds), but that's improbable for FormGen games.
The last two songs, however, are PCM encoded fanfares (originally stored in VOC files), given in two variants - the first is original game, the second is from FormGen Return to Danger and Ultimate Challenge games. Prince never kept any of his original tracks, but he has since remade a couple of the songs to sound like how he originally intended. The music was composed in Sequencer Plus Gold, and then Prince had to downgrade his music to sound proper on the OPL2. The new music was composed by the same artist, Bobby Prince, and it follows the same foreboding vein as the previous game.
The music is very similar in style to that of Wolfenstein 3D (DOS), in fact, much of it is carried over from the the first game.
