I made this thing to add yet another random factor into AEoD: music. Taking as base my old AEoDmus.wad and adding more songs, I made this compilation of MIDI tunes to play with any set of maps. Is not Doom2 exclusive, works in doom1 and I think might work in just about any map around.
Simply put: a huge selection of songs I like in MIDI format. So, per map, it will select randomly one song of the bunch, and loop it for that level. Since there are quite a few songs, and because of the way is made, no song will be repeated in the same playthrough.
Anyway, I realize that the music selection probably wont fit anybody's taste here, because this was primarily made for me and my playthroughs, however this could be used as base for your own personal music randomizer, or whatever

Get it now, while the link is alive

Of course, source is included, and the script is a very small piece of code that can be easily adapted for less or more songs; gotta love MIDIs and their absurdly small file size.
