Well, sure. But this is only useful if you can handle json or are up for finding the right service to export to an end format that you want.
And the only usefulness of this is if you can import your playlists.
You have the titles, albums and artists from your playlist, but no way of listening to them (easily). Thats a high switching cost.
@tjex @thomholwerda this is not true. I have exported playlists from Spotify into Qobuz before and while there were a couple of tracks that weren't there, the playlist worked just fine.
