@Orrelli It is possible... If the TV is off (in Artmode) you can connect via Bluetooth from a mobile phone/tablet or similar to the TV and play music... but beware, it doesn't work with Airplay... you have to connect via Bluetooth...

Also interesting: What "burns in" are discolourations on the wall. I've had the TV in use for 1 year now and already have ugly brown spots on the wall.

The unit goes into art mode when it is switched off, so Spotify cannot be used together with art mode. Other audio sources that run via the TV would also not work because the TV is in standby.

I can't listen to music in art mode.
It is then simply a picture and nothing else... that's how it's meant to be, I think...
