问题
I'm trying to figure out the best way via Spotify's Applescript library to detect a track change. So far, I've tried checking player position -- if it equals 0 it is a new track and the Growl notification appears again. (This didn't work mostly if someone started a song over, etc.)
I'm wondering if the more plausible method is having an idle iTunes script running and checking the current track name for change every couple seconds. I'm worried this might be a bit of a hog memory-wise. I can't get this code to function either.
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
This might be a little complicated but any help is appreciated.

I've worked on a little script, since Spotify does not support Growl 1.3.
Programming is not very good, but I think, the Notifications are very fancy ;)
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 ¬

Worth mentioning this is irrelevant as Spotify has patched this in a recent update.

I have been using this script below. I believe it has the answer to your question in it. This code was found on: http://joonix.se/post/25716608379/spotify-offline-playlist
