You can use Soundiiz to move your libraries. The free tier has some limitations, but you can pay only one month and do it in a matter of minutes, and then cancela the subscription. They cover a lot of streaming services.I use tidal. Pretty good catalog, but their algorithm for suggesting new music blows compared to Spotify. That, and occasionally artists disappear from their catalog. I would probably use Amazon or Qobuz except I’ve got a big library in Tidal. I like that there’s lots of options for streaming to a DAC.
I used it to go from tidal to qobuz and all went well.
