Fwiw I've played with the Spotify api before for managing playlists in my account and that was not complicated. The GDPR export is also computer-readable (json) though it takes a literal month (sleep(rand(10,20)*days) for the initial set, then contact support to also get the "diagnostic" data associated with your account and wait some more). But it's probably more work for you to switch than it's worth.
