Radio Mix only queues seed artist tracks

Support

Issue description:

When starting a Radio Mix from an Artist Page (e.g. The Beatles), the resulting queue contains only tracks from the Beatles, even though Jellyfin returns a valid list of similar artists and those artists have playable tracks in the library.

Additional information:

From the reverse proxy logs I can see the request:

proxy-1  | nginx.1     | tester.com IP_ADDR - - \[18/Jan/2026:19:41:14 +0000\] “GET /Items/c8adebb786bc3c4f0c996e6b1a318a0c/Similar?userId=USER_ID&limit=20 HTTP/2.0” 200 7845 “-” “Symfonium/13.7.0 (Linux;Android 10)” “172.18.0.6:8096”

testing the endpoint with curl it returns valid data:

This is probably the usual Jellyfin bug having multiple internal ids for the artists and returning what they want depending on the case :frowning:

None of the artist Ids returned by the end point are found by Symfonium in it’s database so can’t be used.

Thanks for your reply.

I confirmed Jellyfin duplication issue.

Example: “Genesis” exists under multiple Jellyfin internal IDs:

  • 1b63b20055a1b4bff692e0e3f7c91a84
  • c7fcf9d1ebd9551b28e1bf5c77dbc256

Both have identical ProviderIds:
AudioDbArtist=119229
MusicBrainzArtist=8e3fcd7d-bda1-4ca0-b987-b8528d2ee74e

I also see many similar artists returned by /Items/Similar having 2–3 internal IDs for the exact same Name.

Is this still the same issue from 5 years ago: Problematic API issue with artists / albums · Issue #6048 · jellyfin/jellyfin · GitHub

If yes, thats really a bummer that in 5 years nothing was seemingly done to address this api issue.
Do you know of any workarounds one can do to get sonic analysis features still working in symfonium + jellyfin?

If not is there a music server you’d recommend that has good compatibility with symfonium?

Great app by the way. Absolutely love it. Keep up the good work.

It is the same issue, I’m horrible to have a closed source app, and despite their answer about the API being non sense :slight_smile:

And no I do not have a workaround. I recommend GitHub - epoupon/lms: Lightweight Music Server. Access your self-hosted music using a web interface. or Navidrome but not Jellyfin at all for music but for the moment there’s no AudioMuse AI there.
