Hi guys can you modify this script made by @Emistry?? 

-	script	atcmd_example	-1,{
OnInit:
	bindatcmd "bgm",strnpcinfo(3)+"::OnAtcommand";
	end;
OnAtcommand:
	if ( .can_play ) {
		initnpctimer;
		.can_play = 0;
		playbgm .@atcmd_parameters$[0];
	}
	else {
		dispbottom "Please try again later.";
	}
	end;
	
OnTimer300000:	// 5 minute
	stopnpctimer;
	.can_play = 1;
	end;
}

-	script	atcmd_example	-1,{
OnInit:
	bindatcmd "bgm",strnpcinfo(3)+"::OnAtcommand";
	end;
OnAtcommand:
	if ( .can_play ) {
		initnpctimer;
		.can_play = 0;
		playbgm .@atcmd_parameters$[0];
	}
	else {
		dispbottom "Please try again later.";
	}
	end;
	
OnTimer300000:	// 5 minute
	stopnpctimer;
	.can_play = 1;
	end;
}

Just like in Ragnarok Mobile ..When player listen to it or sit near the npc while song is playing ,the player gains +exp boost and +droprate boost for every minute that he stay near it ,, Maximum of 30minutes a day , so the result will be +30minutes expboost and +30minutes droprate boost
