I just found that Tidal has a “Feed”, provided by the bell in the top-right corner, that shows new releases from favorite artists. It appears to update within a minute or so after adding / removing artists to the favorite artists page. So the basic answer for me is, use Tidal! But I will leave the rest of the post in case it’s useful to others.
edit: It does seem to be missing some releases, unfortunately. Those releases do exist in Tidal and show the correct release date, so I’m not sure why they wouldn’t show up in the feed.
So here’s some things I found:
apparently Spotify is introducing a “What’s New?” feature that might do the trick - although it doesn’t seem to have reached any of my devices
MusicHarbor is an Apple ecosystem app that can import artists from Apple Music (subscription required) or Spotify (no subscription required), and shows new releases for those artists. I found that adding albums from within MusicHarbor to Spotify frequently chose the wrong album, but adding albums to Apple Music got them right.
MusicButler is a similar service, but is a web app, and also imports from Spotify or Apple Music. It doesn’t allow adding to Apple Music, but does to a Spotify playlist. It also sometimes chose the wrong album when adding to a playlist.
- Spotify / Qobuz / TIDAL all have an idea of favorite artists distinct from library albums. Apple Music does not - it just presents a list of all artists for any tracks added to your library.
Basically, it seems like it’s helpful to keep a list of favorited artists in Spotify. There are some options then for tracking new releases and getting them into Qobuz / TIDAL:
- Manually - track your artists in Spotify (which I believe does not require a paid subscription to do so). Use MusicHarbor / MusicButler to find new releases for those artists, then just search for them in Tidal / Qobuz / Roon.
- Automation via Apple Music & Soundiiz - use MusicHarbor to add albums to Apple Music (which in my testing is more reliable than spotify), and then use Soundiiz to sync those albums to Tidal / Qobuz.
- (maybe) Automation via Spotify & Soundiiz - if you already have the “What’s New?” in Spotify then it might give you the list of new releases right away. Then you can manually add them in Tidal / Qobuz, or use Soundiiz to transfer them.
So… it’s a bit convoluted, but possible.
