Record Spotify Tracks for Offline listening (Mac)

I recently stumbled upon a YouTube video that showed how to record Spotify songs on your Mac for offline listening. The easiest way is to use an application called 'Audio Hijack Pro' records audio natively from different sources/applications.
After installing this application, you can record Spotify radio as a single track with a press of a button and then manually split the tracks using any audio splitter/ tool.
I wanted to automate this process and a few more clicks on Google I came across a non-working script which gave me some direction into how this can be achieved.
The script attached below will fire off Spotify and 'Audio Hijack Pro' and when the user selects to record, it will split the songs adding some basic ID3 tags along the way. Have fun.

 tell application "Spotify"  
      repeat  
           try  
                play  
                set currentTrack to (current track)  
                set trackName to (name of current track)  
                tell application "Audio Hijack Pro"  
                     set theSession to my getSession()  
                end tell  
                set loop to true  
                repeat while loop  
                     if trackName is not equal to name of current track then  
                          try  
                               set trackName to name of current track  
                               set trackArtist to artist of current track
