      new SongID;
      if(sscanf(params, "d", SongID))
      {
        SendClientMessage(playerid, -1, "USAGE: /setsong [SongID]");
        SendClientMessage(playerid, -1, "Note: Song IDs: 1 - Ridin' Dirty Song 2 - GTA San Andreas Trailer Song");
      } // SSCANF, if you didn't type a prize the message /setlotto <prize> will show up as a syntax error
      if(SongID == 1)
      {
        Favouritesong[playerid] = 1;
        SendClientMessage(playerid, -1, "Successfully Saved Ridin' Dirty Song! Use /usesong To Listen To It");
      }
      if(SongID == 2)

        Favouritesong[playerid] = 2;
        SendClientMessage(playerid, -1, "Successfully Saved GTA San Andreas Trailer Song! Use /usesong To Listen To It");
