A server-wide music brick exists somewhere, I know because I have itunfortunately I don't know what brick pack it's part of and I'm not going to sort through all of them at 2am to check
I think it was called a 2D music brick
In the recent patch, Server_Servermusic has been removed. Please link add-ons that play music serverside.
Not to be rude, but this goes in suggestions and requests.
