How to get the name of a Radio Station From URL as media_content_id?

Configuration
1

Having this inside a radio configuration:

    - url: http://stream.srg-ssr.ch/m/rsj/mp3_128
      name: Radio Swiss Jazz

…and this as a card:

              - type: conditional
                conditions:
                  - entity: media_player.googlehome5670
                    state: 'playing'
                card:
                  type: markdown                   
                  content: >
                    <b><u><font color= grey> <center>Radio: <br></b></u> [[ media_player.googlehome5670.attributes.media_content_id ]] </font></center>

… and the media_content_id is that URL,
how to have shown in the markdown the name of the radio and not the URL ?
