There are grip, kiai, and dq sounds and even dojo music at start. There is a music file that you can add for music but there isn't custom music that everyone can hear while you fight i thought it would be really cool if there was something you can buy like this in the torishop

Oh god.
Not too bad of an idea, just that the community will abuse it heavily.
Just kiai and grip are enough to make your ears bleed in most cases.
