Problem with the stereo option that so many people have suggested is that the idea is to stealth play the music (name cant show up in-game to other players while playing music).
About the ogg, I am wondering if it is possible to play an over 50kb ogg. I've noticed that all the other player's oggs are in my app folder (so whatever they hear, I can play too). So, in effect, when a player joins, all clients/or server download the joined players ogg files simultaniously. This is probably what causes the lag problem that some people get when a player joins (eventually kicks some people too). I just think, is it possible to hide the file size from the server (like a program that would edit the value of the file size?). Sounds a bit complicated but can there can be bypasses for these files just like there are for pbos?
