DooM music - E2M4: DEIMOS LAB (OPL)
This song hurt my ears on my first session some months ago. Because of this penetrant whistling noise in the background (which are "Tremolo Strings" according the corresponding MIDI-channel (02)). I cancelled it twice over the last couple of months, but today I went to do my job with this song. And "SonicTheJackrabbit"'s request in my profile was another sign to get this finally done. Enjoy :)))
"Skulltag" includes a great OPL-synthesizer which plays the music back "correctly" (our SoundBlaster-card in '95 sounded almost the same). "DosBox"s synth doesn't sound bad, but many instruments are just weird there xD
