checking this one... the desired behavior between the sequence of "pause" followed by "play" would ideally maintain the playhead/timeline position. currently restarts the song.

"play" is currently treated the same as "play some music", which will pick some popular music to play and reset the queue.
It is not the same as "resume playback", which will resume playback from whatever it was before.

If we want the exact word "play" to mean "resume", I think this issue will go together with #704 where we introduce generic "play" / "pause" / "next" / "previous" commands similar to "stop", independent of the normal training.

[tonyespinoza1]

simplest fix for now: it would help if Genie said that they "stopped" the music rather than "paused playback."

Workaround is now merged, it should be deployed in a couple hours.
