i hope this will help you. i don't know if that plugin works or is what you need, but in emit_sound syntax at sample parameter you must put the song path that you want to emit. in the above code i was trying to show you how it should look.

and there already is a plugin that is doing a great job and get s updates when it needs: https://forums.alliedmods.net/showthread.php?p=2117299
