All you have to do, is change

pawn Код:

if(dialogid == DIALOG_MUSIC)
    {
        if(response)
        {
            PlayAudioStreamForPlayer(i, url, x, y, z, distance);

to

pawn Код:

if(dialogid == DIALOG_MUSIC)
    {
        if(response)
        {
            PlayAudioStreamForAll(url);

The stock needs to be anywhere outside any callback.
Don't forget to change url to "link here with the quotes, to let the script know you use a string"
