Just catching up on this thread.
With the release of Plexamp 4.0 you can now pick-up an ongoing playback from one device and continue it on another.
e.g.:
- Start playback of some songs on Plex Web (or another app)
- OpenPlexamp
- Open the
Cast/Flingmenu - Select the app currently streaming (e.g. Plex Web) → Now you can remote control that playback
- Select
This devicefrom theSelect Playermenu → Now the stream is playing onThis devicethrough Plexamp.
In #4:
- the
icon indicates an ongoing stream (next to the song/artist playing) - the
icon seems to indicate that you can takeover the stream from that device

TL;DR: considering this suggestion to be implemented ![]()
