Make a clear rule(s) about spamming music or dance please

[Shinigami l0_0l]

meh... pharmacy and forging and such only got less than 2sec sfx..

but for music? its more than 10 sec...
and when u spam em?? its not even a music anymore.. it just some random annoying noise...

If the people around you are annoying, tell them to can it.??If they refuse, go somewhere else.

this case is kinda same like...
people vend next to the banker/healer in pront... its annoying and hindering u...
but there's still some other banker/healer in the other town..

why do GM put rule(s) on this kind of thing but not for the other hinderance?
