For those of you that care for the REAL experience of doom music, I have uploaded
here a pack containing the genuine doom music.
Those tracks are in mp2 format ( no kidding! ) and were made by the man himself Robert Prince. Now woudl you say, why would those tracks be better than what you get using timidity or some other synthetiser? That's simple, it's because those tracks were produced with the exact same synthetiser Robert used when he created them, and thus only them represent the true vision of the music as it was intended by the author.
As an exemple, compare the original Doom 2 m31 music to any remix or software synth and tell in which you can hear the soldiers footsteps in ;)
All the Doom 1 and Doom 2 musics are in the zip file. Good luck!
