try this

pawn Код:

#include <a_samp>

forward PlayerToPoint(Float:radi, playerid, Float:x, Float:y, Float:z);
forward PlayMuzic(playerid);


public OnGameModeInit()
{
    SetTimer("PlayMuzic", 999, true);
    return 1;
}

public PlayMuzic(playerid)
{
if(PlayerToPoint(1, playerid, x, y, z)
{
PlayAudioStreamForPlayer(playerid,"MUSIC HERE");
}
return 1;
}
public PlayerToPoint(Float:radi, playerid, Float:x, Float:y, Float:z)
{
    if(IsPlayerConnected(playerid))
    {
    new Float:oldposx, Float:oldposy, Float:oldposz;
    new Float:tempposx, Float:tempposy, Float:tempposz;
    GetPlayerPos(playerid, oldposx, oldposy, oldposz);
    tempposx = (oldposx -x);
    tempposy = (oldposy -y);
    tempposz = (oldposz -z);
    if (((tempposx < radi) && (tempposx > -radi)) && ((tempposy < radi) && (tempposy > -radi)) && ((tempposz < radi) && (tempposz > -radi)))
    {
    return 1;
    }
    }
    return 0;
}

its not tested.
