Why interpretor instead of author in a play-list?

[simbun]

I spent a couple of days with a Denon 150 to play with the HEOS app and found the exact same thing, that it wouldn't show me the track artist, be it on the Now Playing screen or when viewing the Album tracks. I tried AssetUPnP and Plex with the same results.

I supplied some logs to @simoncn for some of it's other problems, but didn't investigate the track artist problem directly as it became pretty obvious that I'd have to use an alternative control point if I wanted to use any of the HEOS products.

During my testing I only had one speaker available, so I was never able to test if it was possible to send music from a 3rd party control point to a group of HEOS speakers (which you'd configure within the HEOS app), do you know if this is possible?
