To whomever it may concern:
I dunno what update did this but the music is cancer at the server atm. It doesnt stay permanently deactivated when u type !stopmusic like it used to, I have to turn it off and on again at every round. Also some music I cant remove, and have turned everything off in my csgo settings. A lot of people are annoyed by it. An example of a map with music that wont be turned off is predator at boss fight level 1…
I think it lowers the experience and interaction with the community cause u cant communicate over voip in the server when music is spamming. Imo u should be able to turn off all sounds but voice, I think that would be awesome. Like also zombies getting hit by projectiles and your own bullet sound. But the worst thing rn is the music changes, I really hope its something you guys will consider fixing and can be fixed. 
So maybe you have already been notified by others, but im just posting it to make sure the issue is raised. Have a nice day, thanks
