Request help from Mr Steve JG

Mr Steve last year you were so kind to send me an image of blok editor I need.
Would you be so kind to send me again a new one for my new app?
I would build an App which plays 30 files mp3, containing bible passages, in random manner and when all 30 mp3 have been played the App stops and closes. So Each mp3 must be played only one time till the App stops.
Would you be so kind to show me how the blocks editor mast be set?
Thank you very much.
