¿Monitorea el cambio de pista de Spotify en Applescript?

Question

Estoy tratando de averiguar la mejor manera a través de la biblioteca Applescript de Spotify para detectar un cambio de ruta. Hasta ahora, he intentado verificar la posición del jugador: si es igual a 0, es una nueva pista y la notificación Growl aparece nuevamente. (Esto no funcionó principalmente si alguien comenzó una canción, etc.)

Me pregunto si el método más plausible es ejecutar un script de iTunes inactivo y verificar el nombre de la pista actual para cambiar cada dos segundos. Me preocupa que esto sea un poco sabio para la memoria. No puedo hacer que este código funcione tampoco.

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 

Esto puede ser un poco complicado, pero se agradece cualquier ayuda.

Answer 1

Vale la pena mencionar que esto es irrelevante ya que Spotify ha parchado esto en una actualización reciente.

Answer 2

He trabajado en una pequeña secuencia de comandos, ya que Spotify no es compatible con Growl 1.3.

La programación no es muy buena, pero creo que, las notificaciones son muy elegante;)

set delay_time to 1 

-- register growl 
tell application "Growl" 
set the allNotificationsList to {"SpotifyNewTrack"} 
set the enabledNotificationsList to {"SpotifyNewTrack"} 
register as application ¬ 
    "Spotify" all notifications allNotificationsList ¬ 
    default notifications enabledNotificationsList ¬ 
    icon of application "Spotify" 
end tell

    if ((old_state is "stopped") or (old_state is "paused")) and theState is "playing" then set boolStarted to true 
    if (old_state is "playing") and theState is "paused" then set boolPaused to true
