Music problem!

[Lizard]

When I'm in a level it plays it's music but when I go in a different level which I want it not have music in it! it still plays the music that as played in the other level how can I stop this? i tried doing stopmusic but it just stops the music even in the other level!

my hps file

void OnStart()
{
PlayMusic("02_amb_safe.ogg", true, 1, 4, 1, true);
StopMusic(4, 1);
AddUseItemCallback("", "StorageKey", "StorageDoor", "UseStorageKeyOnDoor", true);
}

void UseStorageKeyOnDoor(string &in asItem, string &in asEntity)
{
SetLevelDoorLocked("StorageDoor", false);
PlaySoundAtEntity("", "unlock_door.ogg", asEntity, 0, false);
RemoveItem(asItem);
}

try to put StopMusic() in OnLeave, so that it stops the music, when you leave the map
