Sorry about taking so long to respond, real life issues and shit with the GF (But that's not important here).
i made some modifications to the music pack: the intermission track's end has been changed to loop better (as well as adding a cymbal to the beginning of the track as that really bugged me for some reason), the D_MESSAG tracks have the Power drumkit now like it's supposed to, and D_ADRIAN has been replaced with a new track, Memorical Subligations: Sleep Deprivation is now in as an unused track in the pack called D_SLEEP.
also, for some reason Slade decided to nuke the contents of my text file inside the music pack. i can't fix it right now though so i'll have to do it later.
edit: some other track changes: D_READ_M has been replaced with a new track called Child's Play. the old track, The Icarus Rises Again, is in the pack as an unused extra called D_ICARUS.
the biggest change right now is that D_AMPIE has a temporary candidate now! it now houses the track TOTALLY AMERICAN METAL, which i'm contemplating about whether it makes a good fit for a Doom 2 track or not. please tell me what you think about it.
edit2: some more changes! D_SHAWN2 and 3 have been replaced by a original song, Blazing Insignia. the original song is in the pack as D_ROCK now. there's also some new bonus tracks in it now: D_NOTITL (Untitled Game Track), D_WONDER (Wonderstrike), D_UNNAME (Unnamed DNB Track), and D_SPIRAL (Sandy Spirals).
edit3: actually, you know what? Ascension of Satan is D_SHAWN2 and 3. Blazing Insignia is bonus track D_BLAZE now. fuck what my thoughts about AoS is, it's just a better fit for those slots.
Same as before, if I were to put these tracks in a wad these would be the themes I would chose for the maps:
D_AMPIE: This track is great! However it feels more like it would fit Ultimate Doom or TNT (Due to how fast paced and god damn awesome it is, it would go great with those IWADs gameplay but not Doom 2's in my opinion). This track would be best suited to fast paced gameplay, I can't really think of a specific theme but I would put it in hell (because that is where the wads difficulty would be at its highest).
D_READ_M: This sounds military to me, the drum snares make me think of a march but the jingles also add a layer of mystery to it... If this was used as a level track I would use this in an assault on a hostile military compound (with hellish elements to it) with relaxed and slow progressive gameplay.
D_ADRIAN: This track makes me think of Duke 3D, Chex and TNT all in one (I have no idea why though, probably because some parts like the start remind me of chex, the background sound reminds me of "Rabid Transit" from Duke 3D and the main part of the song reminds me of TNT). This track would go well in a underground instillation (Like a cave or even a subway), the somewhat deep tone and "Deepest Reaches" like jingle give me sense of claustrophobia (but not as in 64 wide corridors, as in trapped in a cave).
D_NOTITL: This track makes me think of a neon city with signs, lights and bars everywhere. It gives me a very neo future vibe from it, almost like an 80's future kind of feeling (The one where everything is some sort of cyber-thing, like cyborgs and flying cars). This would go great in a cyber-city or future setting. If I were to think of a name for it, I would call it something cheesy like "Neon Nightmare", "City Night Fight" or "Glowing Utopia"... But that isn't exactly preferable.
D_WONDER: This track also makes me think of the cyber future, but a more mysterious side of it, this track would go excellent in an unknown building or ship (like an organic powered factory/space craft with a blend of tech and flesh textures used) with dark and foreboding lighting.
D_UNNAME: This track would honestly be great for the list of characters at the end of the Doom 2 IWAD or the end story music (unfortunately you can't separate story screen music from each other, I think that is impossible to do outside of ZDoom), if used as a level track I would use this as a track played in a storage facility (with obligatory crate maze) because the nature of the track feels like you should be in a hurry to get out (Like have a cyberdemon roaming in that maze with you, or an army of pinkies... That would be nerve wrenching fun!).
D_SPIRAL: This track makes me think two things: Spyro and MAP31 of TNT. I think MAP31 of TNT because I think this track would go great with an ancient temple of some sort (like an Aztec or Egyptian one filled with mystery, jungle/sand and traps), the mysterious and somewhat desert sounding tune behind it just fills me with visions of sandy bricks. I think Spyro because this track gives me the idea of exploring a temple (And temples are a recurring level theme in Spyro games), it also sounds mysterious but actually kind of joyful as well (kind of like an Easter Egg level?).
D_BLAZE: This one gives me feelings of a church/chapel (mainly because of the bell like noise that plays throughout) I would generally sort this track into a graveyard map (The track also kind of reminds me of a Duke 3D level, can't recall what level it was though), a bloody and brutal assault against zombie type enemies up a cemetery hill to get to the church upon said hill, but I also get cavernous feeling from this track (but a more open and explorable one than what one would expect).
Now did I miss any tracks or did I get them all? It gets really confusing loading up a random Doom 2 map then using "changemus D_XXXXX" so do tell me if I missed a track or two.
