Music problem?

[Zypherzemus]

Ok, I'm trying to set up music between 4 different levels, hub level playing one track in the beginning when you first enter the map, then once you leave to another level, it stops (This part is true) Heres the problem, once I leave the first level and go back to the hub level, the music from the first level continues to play, even though I put the "StopMusic" command in the "OnLeave" section on the .hps file for that particular map. and I wouldn't know how to play a different track once you re-enter the hub level, help?
