What originally was a silly little fork of PizzaTower and SCPEscapeMusic has now become a full plug-in for FacilityMeltdown and now LETHAL RESONANCE MELTDOWN! Just set the MusicVolume to 0 and MusicPlaysOutside to false in FacilityMeltdown's config
You can you select what genres of music you'd like to listen too! Include/exclude whatever you want but make sure MASTER IS ALWAYS FIRST

Metal Black Betty, Click Click Boom, Dividing by Zero, Jump Da F*ck Up, Last Resort, Let's Start A Riot, Not Ready To Die, Shepherd Of FireZombies Treyarch Zombies 115, Abracadavre, Always Running, Beauty Of Annihilation, Damned, Not Ready To Die (zombies ver.), Pareidolia (instrumental), Where Are We Going80s Holding Out For A Hero (Shrek 2 ver.), Livin On A PrayerEDM Fight Dirty, Seven Nation Army (Glitch Mob), Womp PortalMeme Neon Tide, Plan Z, My WayVideoGame Doom, Final Flash, The Only Thing They Fear Is YouClemV1 Ambient sounds/10:30pm alert music included in Version 1Now fully integrates LETHAL RESONANCE MELTDOWN to have a small chance (10% currently) to trigger its Meltdown Sequence on it's own without music overlayed. Add LRMeltdown to the end of the list. 
LETHAL RESONANCE MELTDOWN Must Be Installed To Function.
If you ever Uninstall this in favor of LRMeltdown you must change the script to Defaultfor LRMeltdown to function properly again
When you load into a save it will stutter for ~10 seconds, that is the sounds being loaded. This is unfortunately unavoidable due to the number of songs being loaded by default (and they fact they are .ogg (.wav loads fine but that would make the mod ~1GB) You can now decide what genres you would like to load! Should help with load time but Metal/Zombie is still alot of songs
