Monitorowanie zmiany ścieżki Spotify w Applescript?

Question

Próbuję znaleźć najlepszą drogę za pośrednictwem biblioteki Spotify's Applescript, aby wykryć zmianę śladu. Do tej pory próbowałem sprawdzić pozycję gracza - jeśli jest równa 0, jest to nowa ścieżka, a powiadomienie Growl pojawia się ponownie. (To nie działało głównie, gdy ktoś zaczął piosenkę, itp.)

Zastanawiam się, czy bardziej wiarygodną metodą jest posiadanie bezczynnego skryptu iTunes i sprawdzanie aktualnej nazwy ścieżki w celu zmiany co kilka sekund. Obawiam się, że może to być trochę mądrość w wierze. Nie mogę również uruchomić tego kodu.

tell application "System Events" 
    -- checks for instance of Growl and Spotify, does not run if both programs are not active 
    set isRunning to ¬ 
     (count of (every process whose name is "Growl")) > 0 
    (count of (every process whose name is "Spotify")) > 0 
end tell 

--establish empty variable to be filled by song title later 
global latest_song 
set latest_song to "" 

on idle 
    tell application "Spotify" 
     if player state is playing then 
      copy name of current track to current_tracks_name 
      -- runs match between last and current song titles 
      if current_tracks_name is not latest_song then 
       copy current_tracks_name to latest_song 
       set who to artist of current track 
       set onwhat to album of current track 
       tell application "Growl" 
        -- Make a list of all the notification types 
        -- that this script will ever send: 
        set the allNotificationsList to ¬ 
         {"SpotifyNewTrack"} 

        -- Make a list of the notifications 
        -- that will be enabled by default.  
        -- Those not enabled by default can be enabled later 
        -- in the 'Applications' tab of the growl prefpane. 
        set the enabledNotificationsList to ¬ 
         {"SpotifyNewTrack"} 

        -- Register our script with growl. 
        -- You can optionally (as here) set a default icon 
        -- for this script's notifications. 
        register as application ¬ 
         "Spotify" all notifications allNotificationsList ¬ 
         default notifications enabledNotificationsList ¬ 
         icon of application "Spotify" 

        -- Send a Notification... 
        notify with name ¬ 
         "SpotifyNewTrack" title ¬ 
         current_tracks_name description ¬ 
         who application name "Spotify" 
       end tell 
      end if 
      return 5 
     end if 
    end tell 
end idle 

To może być trochę skomplikowane, ale każda pomoc jest doceniana.

Answer 1

Warto wspomnieć, że jest to nieistotne, ponieważ Spotify naprawił to w niedawnej aktualizacji.

Answer 2

Pracowałem nad małym skryptem, ponieważ Spotify nie obsługuje programu Growl 1.3.

Programowanie nie jest bardzo dobra, ale myślę, że Powiadomienia są bardzo fantazyjne;)

set delay_time to 1 

-- register growl 
tell application "Growl" 
set the allNotificationsList to {"SpotifyNewTrack"} 
set the enabledNotificationsList to {"SpotifyNewTrack"}
