Loop from a list syntax

Configuration
1

Hello,
I use this part of code to select a webradio in an action.
But as the list is short, there is often multiple time the same source.
I’d like to select the radio one by one following.
How can I adjust the syntax ?

Thanks for your help !

service: media_player.play_media
data_template:
  entity_id: media_player.audiobureau
  media_content_id: >
    {{ ["http://strm112.1.fm/ajazz_mobile_mp3",
    "https://radios.rtbf.be/classic21-128.mp3",
    "https://radios.rtbf.be/laprem1ere-64.aac",
    "http://icecast.vrtcdn.be/stubru-high.mp3",
    "http://stream.funradio.sk:8000/fun128.mp3",
    "http://belrtl.ice.infomaniak.ch/belrtl-mp3-192.mp3"] | random }}        
  media_content_type: audio/mpeg

I modified my code to exclude the current playing radio. I think it’s the best solution.

service: media_player.play_media
data_template:
  entity_id: media_player.audiobureau
  media_content_id: >
    {% set current_radio = state_attr('media_player.audiobureau', 'media_title') %}
    {% set radios = ["http://strm112.1.fm/ajazz_mobile_mp3",
                    "https://radios.rtbf.be/classic21-128.mp3",
                    "https://radios.rtbf.be/laprem1ere-64.aac",
                    "http://icecast.vrtcdn.be/stubru-high.mp3",
                    "http://stream.funradio.sk:8000/fun128.mp3",
                    "http://belrtl.ice.infomaniak.ch/belrtl-mp3-192.mp3"] %}
    {% set available_radios = radios | reject('equalto', current_radio) | list %}
    {{ available_radios | random }}
  media_content_type: audio/mpeg
