Music stops too soon

[zombiehacker595]

so this is my music script and it only lasts for like 15 seconds and i thought the 450.0f was seconds so im confused how to get it to gor for longer? thanks

PlayMusic("10_amb.ogg", false, 3, 3, 3, false);
AddTimer("stop", 450.0f, "Stop");
}

void Stop(string &in asTimer)
{
StopMusic(2.0f, 1);
}
