The only music we included for DC are the original .midi files. If you are hearing the HRP version, EDuke32 must be finding them on your system and playing them for you. I think it looks in a few places for installed Duke 3D and will play oggs of the same name as the midis.
All right, maybe I said the wrong thing. I said "HRP version" because I remember back in the day when Megaton was new, there were topics asking why the music was missing, as Megaton's DC episode reused the episode 3 tracks (which, to my understanding, is how it always was). The replies said that all the extra music (X-Files theme, Tyrian/Jill of the Jungle tracks, etc) were from the HRP version and that's what stuck with me for some reason. (Also imagine being a brand-new Duke player in 2013, suffering through the Smithsonian map for the first time, going online to look up videos and hearing completely different music from what was just in the game.)
I went into the Alien Armageddon folder, in music, under DC, and listened to the midi files in there, those sound like what I just heard in the mod. Top Secret's music also worked for me, if that helps anything.
Sorry for the confusion.
