I've been wondering this because i've seen such a thing used on many different servers, a good example would be pecon7's server, and it seemed to broadcast the music completely serverwide without client mods like 2D music. how could i do this? oh and by the way, the music brick they used broadcasted the sound so that it wouldn't get super loud unless you got really close to it.
if you're wondering why i need this it's because i'm gonna be hosting a space TDM and i need just 1 music brick to cover the entire area/map. that way the music stays synchronized always. if i used multiple 5x range music bricks, people walking from one part of the map to the other would hear two copies of the music completely out of sync.
