I just want to share my experience with the Moment. I love it. No reboots.
First I started with DLNA. And yes, the Moment had problems with the covers. But why using DLNA? I started to add all of my albums as favourites in deezer. Only a few artists were not available. In sum I have only 50 songs still on my NAS available via DLNA. This is working very well.
I hope that in future it is possible to search directly in deezer with the Moment. And we will see a better integration in NL/ML configurations. Now the speakers in the main room switch on when you hear music in any link room.
All in all it is possible to use it now. And an update is on the way as I read hear in the thread.
