The release is building, but you can already try Subsonic support from the DSub android client (https://f-droid.org/en/packages/github.daneren2005.dsub/) with the demo #funkwhale instance.
Download the app, add a new server with the URL https://demo.funkwhale.audio, and login with demo and demo as username and password.
Check the 'Browse by Tag" in the server settings, it's important.
