[All Platforms]Listening shuffled, to ALL songs of ALL my playlists without interference.

[Cees99]

I have >6000 songs, stored in playlists under its Artist name.

I would like to listen to all these >6000 songs shuffled without any
interference.

(This is the way I want to listen to Spotify on my Hifi device).

I have tried to put all >6000 songs together in 1 playlist, but since
spotify is using a queue of about 100 songs, Spotify stops at the end of
this queue, So this is not the way.

Also tried to use "Radio", but this is even worse.

Any ideas how to make this way of listening more easy?

If there is no solution, Spotify, shouldn't it be a good idea to have this functionality?

My devices:

Bluesound Node 2 (Spotify connect)

iOS (I-phone and I-pad)

Desktop (for maintenance playlists)
