DoomDynMusic mod (originally made by cyber_cool) that I've put together on Painkiller Black Edition.
Simply drag and drop on your launcher of your choice and enjoyed!
Here's the summary of how the system works:
1. When their little to no enemies present in the map, the music will shift to normal (or ambient) music.
2. If there enemies present in the map (depends on the amount of enemies detected via setting), it will change to action music, but when all the enemies are down, the music will go back to normal.
3. When their multiple amount of enemies or a boss in the map, it will play the special track called the "high action", where basically it plays boss-like intense music and it will only change if it occurred. Otherwise, when you kill more monsters, it will go back to action music.
4. Depends on the music pack, some contain more than 1 or 2 tracks on the string, to quote the creator themselves:
"DoomDynMus picks a random chunk first (from any music chunk file loaded), then it picks a random track inside this chunk, according to current state of the game (ambient/action/death/high action). Each chunk has an equal chance of getting picked, no matter how much tracks does it have." - cyber_cool
5. You can tweak it via CVars option of how many enemies detected you, fade in and out of the track, range of enemies, and how much amount of enemies until high action music plays.
