Qobuz will transfer all of their playlists for free in just 2 clicks, it's part of their onboarding. And their music will suddenly be higher quality to boot, and the artists actually get paid for streams. Just letting you know your options.

They won't lose their playlists. When you cancel premium it just switches to the free plan. They'll have ads and won't always be able to play the exact song they want, but otherwise everything else will remain exactly the same.

There is https://soundiiz.com/ which works really well even with their free tier. I think I have transferred all my playlists from Spotify > Apple Music > Qobuz > Youtube Music` by now :) Unfortunately it does not help with convincing family members :(

Now if I want to cancel it and they lose their playlists, they’ll be all pissy.

I did a quick search with duckduckgo and found this: https://exportify.net/

Yeah the upside to my kid being able to explore music and have that whole world opened for him outweighs moving to a different, but still shitty in various ways, music streaming service.

If you cancel the paying plan people can still login and use in a free/ad supported version or not? So nothing lost.
