Audio player web page

Web page which starts playing audio file(s) when user enters to the page (I know this difficult one, so it is ok if user has to press play button in first time)
After the first audio file is played the page should play (automatically) next audio file.
Audio files are played based on audio file date information so the newest is played first and the oldest last.
The same audio file should not be played again to the same user.
- if cookie is used to remember the played file and the user has cleared the cookies then all the files will be played again following new user rules.
If the audio file is older than 48h (configurable parameter in the code) then it will not be played even if the user has not heard it.
When all the playable audio files have been played then the page should play endofaudiofile.mp3 audio file.
Use cases:
1. User comes to the page first time - play the newest audio file and keep playing all the audio files which are newer than 48h and after all is played play endofaudiofile.mp3 audio file.
2. User comes to the page and last time s/he listened the newest audio file, play the second newest audio file and keep playing all the audio files which are newer than 48h and after all is played play endofaudiofile.mp3 audio file.
3. User comes to the page and has listed all the audio files in previous time - play endofaudiofile.mp3 audio file.
4. User comes to the page and all the audio files are older than 48h - play endofaudiofile.mp3 audio file.

Please propose how this should be done.
My preferred platforms are
1) Standalone solution
2) Wordpress function(s) in childtheme functions.php file (easier than doing plugin)
3) Laravel 5.6
