I discovered only now that we can have, when creating an automation with the play-media-action and picking up a radio station from the Radio Browser integration, metadata like title and the thumbnail of the Radio.
This is what i get in yaml mode of the automation.
metadata:
title: Art Of Music
thumbnail: https://artofmusic.fm/apple-touch-icon.png
media_class: music
children_media_class:
navigateIds:
- {}
- media_content_type: app
media_content_id: media-source://radio_browser
- media_content_type: music
media_content_id: media-source://radio_browser/country/IT
