Hectic theme heard in the final dungeon of SMRPG, its fast percussions and metallic sounds invoke an industrial feeling. Obviously fit for dangerous/industrial areas.
Note that it does not include the SMW thunder sample.
Daizo Dee Von It inserted for me, but yeah lowering the echo delay is the least harmful way if you have problems.
Edit: I've reuploaded it with more optimized samples, so maybe now it will insert for you without any issue.
