[@NeoAC] Alright, lemme start off by saying that I [b] LOVE [/b] the idea of music as a weapon in a world that runs off of music. 

I might have this next part completely wrong but, I don't think that all of the threats in the DgtWld exist outside of the DgtWld. I think that there are also a lot of viruses that need to be fought, so maybe if your music acted as a more physical blast than just high frequency sound?
