Correct me if I'm wrong, but I believe the circumstances under which Spotify would have permission to read your messages are 1) if you use their Messenger app plugin 2) if you had connected to Messenger through Spotify's desktop app. I believe this feature has been deprecated for a few years now, though. Even if you sign up for Spotify using your Facebook account or connect your Facebook account to Spotify that does not give them access to your Messenger messages. It is my understanding that it required the user to opt into specifically connecting Messenger for that circumstance to occur.
