While no user has mentioned this, it has come to my attention that my server is no longer adding plays from Play Music, Pandora, etc, to your Spotify playlists. After some digging, I found an issue in my code that has rendered this feature useless for a few months. 🙁
The good news? No information was lost. The server is busy fixing things up as I type this and in a few days this feature should be working again. Anything you listened to outside of Spotify will magically start appearing in your Songlytics playlists in Spotify.
