Ok, so whatever flag that tells "Play this music at this spot" is on the client? Boo that sucks. I was curious since I was tinkering around with some Java AI files and I found the "PlaySound" command that lets me play whatever OGG file I add to the Music folder. I thought that applied to the zones and that the server had a flag that would send the packet of what music to be played.
But yes, what you said has some sense to it. I'm also guessing there is no way to work around it, like making a script that will force to play a music file once you enter an area, right?
