Good list. I added to likes:
- Federated search across streaming platforms and local library
- Search can even be a label, or smart search through a composer or artist with multiple spellings
- Ability to see artists on tracks and find their work (e.g. listen to Joey Alexander, say “ooh, that drummer is great” and follow on to albums with Eric Harland or Ulysses Owens...
- Pretty good internet radio integration
- can cast to chromecast, including chromecast groups
Added to dislikes:
LMS can do this and many other things too at no cost.
