In the regular Plex application (I use Windows, Android phone, Android TV/shield & Panasonic TV), if I open an “album collection” which is sorted randomly and I play the first album, it will queue all albums in the displayed (random) order.
When I do the same in PlexAmp, instead of queueing the album collection in the displayed, it queues all albums by the same artist instead.
This makes it impossible to queue a selection of albums (“collection”) in a random order (but not shuffled).
Also this behaviour is unexpected, both from a blank POV, as when used to using the regular Plex application for playback.
I only use Plexamp on my Android phone, but noticed the windows version behaves the same. I think this unexpected behaviour of Plexamp will happen on all platforms.
