Upload Your .mp3 in DropBox.com, When you upload it right click on it and click share link, then when the tab opens copy the URL and make sure there is .mp3 at the end of it, then make dropbox.com in the url dl.dropbox.com

Example :

pawn Код:

PlayAudioStreamForPlayer(playerid, "https://dl.dropbox.com/s/fa5jtpuf2eae0hm/Jingle%20Bells.mp3");
