Use Audio Hijack Pro to record Spotify tracks while you listen

Spot the Hijack

* Script to record and tag spotify tracks, by Lloyd Moore *)
(* Make sure you are already recording in Audio Hijack Pro with a session called 'spotifySession' *)

tell application "Spotify"
	set currentTrack to (current track)
	set trackName to (name of currentTrack)
	tell application "Audio Hijack Pro"
	    set theSession to my getSession()
	end tell
	repeat
		if trackName is not equal to (name of currentTrack) then
			set trackName to name of current track
			set trackArtist to artist of current track
			my recordTrack(theSession, trackName, trackArtist)
		end if
		delay 1
	end repeat
end tell

on recordTrack(theSession, trackName, trackArtist)
	tell application "Audio Hijack Pro"
		tell theSession
			split recording
			set output folder to "~/Desktop"
			set output name format to "%tag_title -- %tag_artist"
			set title tag to trackName
			set artist tag to trackArtist
		end tell
	end tell
end recordTrack

on getSession()
	tell application "Audio Hijack Pro"
		set sessionName to "spotifySession"
		try
			set theSession to (first item of (every session whose name is sessionName))
			theSession is not null
		on error
			set theSession to (make new application session at end of sessions)
			set name of theSession to sessionName
		end try
	end tell
	return theSession
end getSession

Any chance to extract the song number of the album and put in the filename? Like 01-artist_titlle.mp3 etc?

seems useless... can anyone get this to do anything besides freeze?

Here is a working script: http://joonix.se/post/25716608379/spotify-offline-playlist

I know this thread is a little old now, but I was still having problems with the file splitting and tagging properly (even with balboah's update). I cobbled together a few similar scripts to get one that works for me; see my fork of this gist (https://gist.github.com/tiffanygwilson/1914c3b7724e65d736f6). I also added some automation for starting/stopping Spotify and the recording session and the option to select the output folder upon running the script.
