I've been using Qobuz (along with my own Navidrome instance) for the past year. The depth of music in some genres seems pretty good, and seems to have all the mainstream artists, but once you get past them in indie/pop/rock genres the gaps in the catalog really start to show. I've reached out to some artists, and no one seems quite clear why their releases don't appear in Qobuz when they appear in all of the competition. Unfortunately, none of the competition makes lossless streaming available (and I'm not counting Tidal's MQA, even if it was available on Linux).

When I joined they had some social features, and searching for user created playlists seems possible. The last couple of times I've tried I've only gotten Qobuz's official playlists in search results. I've had to make do with syncing playlists from Spotify with Soundiiz.

When combined with how inaccurate the metadata is (including the lack of ability to report the inaccurate metadata) and the lack of any new features in the past year (including lack of copying pre-saves from every other platform), it really seems like investment in Qobuz has stalled.

It's too bad, because it seemed pretty promising. I really miss Rdio. :'(

For listening to Navidrome on the go I use the "substreamer" app on Android. The "Podcast Republic" app also works well for listening to college radio streams to find new artists.
