The music is very awesome and when awesome music comes into question I tend to like to find out where it comes from (partly so that I might find some more of it!)
As for textures - the main reason here is because of the N_MTTK* set - Skulltag has like 1-20 + 62 + 63 and Stronghold has more of them, but apparently not all. I'm trying to find these "missing textures" - I'm a mapper myself and am always looking for new resources.

Thanks in advance.
