I recently discovered that spotify (Windows desktop version) could browse my local files and if they existed on spotify I could click on the song/artist/album and be taken to the page, where I could follow/add etc. I was happily making my way through the list for hours, rediscovering old favorites and finding a lot of new gold along the way.
Then the "update" happened. Along with several other features that were removed, I can no longer click on any of my local files to access the corresponding spotify pages. This is a huge letdown, as I was looking forward to continuing my journey.
