Logitech Squeezebox command for next/previous track?

Third party integrations

I was wondering if anyone could advise me of the correct JSON service data to use with the Logitech Squeezebox squeezebox_call_method if I want to skip to the next or previous track? I’ve tried the example below (to skip to the next track) but it didn’t have any effect:

{ “entity_id”: “media_player.lounge_tv”, “command”: “playlist”, “parameters”: [“index”, “+1”] }

    - service:  media_player.media_next_track
      data_template:
        entity_id: "media_player.{{states.input_select.lms_player.state}}"
