AUDIO-DINSTP and Spotify account

[toujour]

Hi,
I not found any information about Spotify account with Audio-DINSTP.

It works by transfer from a smartphone in the same WiFi or the device has an its account inside (I prefer) ?

(  I have a guest room so I'm looking for a solution with some playlist from a wall buttons and no other devices )

BR,
Alberto
