I'm not sure if it's an update to goldsrc between sven 3.0 - 4.8 that broke this but
would it be possible to make music consistent during map change?
i. e. it continues to play without interruption

I guess, with all this music software, and alt-tabbing taking less than a second to find my music folder could be one thing
but I also liked how the sounds were subject to the game's room-echo filtering (underwater or room that echoes)
Maybe an extra feature for SC 5.0?
