Sound Spawn in the Demons Hand Music Mod (Need Help)

[Bozeefus]

I need help. I'm completely new to the modding scene, I have zero experience whatsoever and was wondering if I could get a little help.

Don't get me wrong, I do LOVE the music for this game, despite not like Metal AT ALL but I wanted to mod the music and give it a little twist with these badboys:

[Helipad - Soliel's Stage]

[Dark Forest - Vindicator/Angel Teneres Stage]

[Inferno - GateKeeper/Black Brimstone Stage]

So can anyone help a modding beginnner out>?
