First write your code like this:

PHP код:

if(dialogid == DIALOG_Music)
{
    if(!response) return 1;
    SetPlayerScore(playerid,GetPlayerScore(playerid)-25);
    sarkibasladi = true;
    SetTimer(!"@endMusic",1000*60*3+1000*30,0); //Then this is called after 3:30min (a song is ~3:30min)
    foreach(new i: Player){
        PlayAudioStreamForPlayer(i,inputtext);
    }
    return 1; // We handled a dialog, so return 1. Just like OnPlayerCommandText.
} 


You should do it static...

PHP код:

@endMusic();@endMusic()
{
    foreach(new i : Player) StopAudioStreamForPlayer(i);
    return sarkibasladi = false,1;
}
