Upvoted! First of all, music streams can cause lags for the people with slower internet connection. I occasionally play running around with guns when there is suddenly a party with intense music streaming, which caused high ping and
"fighting disabled", or even kicked from the server. It's pretty annoying in term of gameplay.
It's annoying too when the speaker plays some kind of trashy music which you don't like that could also burn your ears; that situation is when turning off of it is mandatory.
