监控Applescript中的Spotify轨迹更改？

我正试图通过Spotify的Applescript库找出检测音轨变化的最佳方法。到目前为止，我已经试着检查玩家的位置——如果它等于0，这是一个新的曲目，咆哮通知再次出现。（如果有人重新开始一首歌，这通常不起作用，等等）

我想知道是否更合理的方法是让一个空闲的iTunes脚本运行，并每隔几秒钟检查一次当前曲目名称的更改。我担心这可能是一个有点猪记忆明智。我也不能让这个代码正常工作

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

这可能有点复杂，但非常感谢您的帮助。

值得一提的是，Spotify在最近的更新中对此进行了修补。

我编写了一个小脚本，因为Spotify不支持Growl 1.3
