Get track info when action (iTunes Applescript)

The easiest way to do this is if you know how to write a cocoa application because every time something changes in iTunes it send out a system wide notification. A coca app can receive that notification and take an action.

Since you want an applescript method then you must do it the hard way. You'll need some variables to keep track of the current song and player state. Every time through your repeat loop check the current song against the song and player state you have stored in your variables. If something changes then you can take an action.

I didn't test this but it shows the idea. I hope it helps. Good luck.

property savedSongName : missing value property savedPlayerState : missing value repeat delay 1 set somethingChanged to false tell application "iTunes" set currentTrack to current track set currentSongName to name of currentTrack set currentPlayerState to player state if currentPlayerState is not savedPlayerState then set somethingChanged to true else if currentSongName is not savedSongName then set somethingChanged to true end if if somethingChanged then set myAlbumiTunes to {get name of currentTrack, get artist of currentTrack, get album of currentTrack} log myAlbumiTunes end if set savedPlayerState to currentPlayerState set savedSongName to currentSongName end tell end repeat 

EDIT: if you do write the objective-c program, just register for the notification as follows.

[[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(receivediTunesNotification:) name:@"com.apple.iTunes.playerInfo" object:nil]; 

Then create a handler "-(void)receivediTunesNotification:(id)notif". That will be called whenever something changes. You can get a dictionary from the notification that gives the change information as follows.

NSDictionary* itunesDict = [notif valueForKey:@"userInfo"];
