@killyourfm Just in case it might help, when I jumped ship a few years ago (for Tidal, which at least pays artists a little bit better), I used this free service to copy all my playlists over: https://www.tunemymusic.com/
Pros:
- does what it says on the box
- costs nothing
- doesn't take an obnoxious amount of time
Cons:
- will replace tracks it can't find on your new service with somewhat random ones
- will delete your playlist descriptions and replace them with "created with Tune My Music" text
