Media_content_id: playing multiple mp3 files

2 Question and hoping to get some answer:

Would like to know if there are a possibility for media_content_id to play multiple mp3 sound?

          media_content_id: >-
            - /local/sounds/1.mp3
            - /local/sounds/2.mp3
          media_content_type: audio/mp4    

If this possible is there away to run random multiple mp3? Not really good with python so maybe someone can assist.
