I'm fuckin loving it already. Even linked up to import my Apple Music library through a third party service. I'd say it got about 85% right. Others are just the odd thing like tracks are mixed between the normal and deluxe edition of albums, others are the clean version for some reason, but no big bother and most are correct.
The service itself is great. Responsive good UX. Not noticed anything missing in the library.
Just hoping the algorithm learns my tastes and recommends stuff I like, Apple Music, Tidal, and Spotify are all good at that. I'll find out in the next few days as I use it more.
First impressions are very good though!
