I wonder if they'll explore other music services as well. As I understand it, Deezer, Qobuz, and Tidal can all get ripped easily enough. Although I'm not sure if they rate limit downloads past a certain point.
I'm a bit sad that they chose to focus on music rather than audiobooks. Creating an archive of audiobooks seem like it would be more aligned with their mission.
The metadata is gold, but I was immediately curious why why wouldnt go for Tidal first. Though what ever they have on Spotify I think is unique.
