Save albums for all tracks in my Spotify library

In June 2019 Spotify rolled out an updated UI which included some significant changes to a user's library. I noticed a lot of traffic on a small app I made a few years earlier. Turns out my 'follow all artists' app was proving to be very useful to other Spotify users. Some people were looking for similar functionality to save albums, so I've tweaked the code and voilà!

Simply login with Spotify and the app will fetch all the songs in your library, identifying the albums they're on and whether the albums are already in your library or not. Select the albums you want to save (hit the select all saved button to speed that up) then hit [Save All Selected] to save all of them at once.

You can also use this tool to bulk remove albums from your library. Just select the relevant albums and hit the [Remove All Selected] button.
