from pprint import pprint
from mpris2 import Player

uri = "org.mpris.MediaPlayer2.psst"
player = Player(dbus_interface_info={"dbus_uri": uri})

pprint(player.Metadata)

Outputs:

{dbus.String('mpris:artUrl'): dbus.String('https://i.scdn.co/image/ab67616d0000b2731f829ea9c2c7ffcec1a3c857', variant_level=1),
 dbus.String('mpris:length'): dbus.Int64(152560000, variant_level=1),
 dbus.String('mpris:trackid'): dbus.ObjectPath('/', variant_level=1),
 dbus.String('xesam:album'): dbus.String('Unknown', variant_level=1),

For comparison, Spotify official client outputs:

{dbus.String('mpris:artUrl'): dbus.String('https://i.scdn.co/image/ab67616d0000b273edf76e6cc66ec0dee12273c1', variant_level=1),
