Auto play entire collection on shuffle

I am trying to migrate from Kodi (w/ OpenElec) to Volumio.
I am loving Volumio, despite a few bugs, but there was a major feature I had in Kodi that I’m missing a lot.
I had PartyMode which was a setting that enable Kodi to auto play on startup my entire collection on shuffle.
As I don’t have that on Volumio I am trying to develop something to get me this.
Can some shed some lights on how to achieve this?
Maybe a python script on startup along with Volumio Web API?

Nice feature indeed, we’ll add in next versions!
