Custom Music tutorial by SirNugz

I have corresponded regularly with SirNugz about mod building and music and 2da files. He and I both went through a good deal of pain figuring all out how to add music and add custom content. He has published a guide on NWVault showing the ins and outs of adding customer music to NWN2. Check out SirNugz tutorial here.
