Replacing music in Heroes III.

My music has been partially replaced: Castle – replaced with the *Haven* castle from Heroes 6. Tower town – themed after the Protoss from StarCraft 2. Dungeon town – themed after the dungeon from Diablo 1. Swamp town – themed after the Hive from Diablo Hellfire. Orc town – themed after the Orc town from Heroes 6. Colony town – themed after the Sanctuary town from Heroes 6. Inferno town – themed after the Hell from Diablo 1. Snow – replaced with snow from Heroes 4. Sea – replaced with sea from Heroes 4. Grass – replaced with grass from Heroes 5. Dungeon – seems to be some track from Heroes 6. Deadlands – replaced with an analogue from Heroes 5. Battle 1 – replaced with the Haven battle theme from Heroes 5. Battle 3 – themed after the humans from StarCraft 2. The rest remains unchanged. I'm looking for something for the Necropolis town, but haven't found anything suitable yet.
