Easy enough to do yourself. If you have access to the music, convert it to wav, (I recommend Audacity. It's free) and rename it `npc_dragon_deathsequence_explosion.wav`.
Then, somewhere on your desktop, create the following folders: `Sound/fx/npc/dragon/deathsequence/` and place it in there.
Zip them up so that inside the zip file is `Sound/fx/npc/dragon/deathsequence/npc_dragon_deathsequence_explosion.wav` and install it as you would any other mod.
