relatedly, songs may still be marked as already played (slightly greyed-out) may make seprate issue for this

note song "21 guns"

also also: by "now playing indicator" i mean the purple text & bars animation, the indicator at the top of the screen is correct.

seems it may be able to also duplicate song entries in queue... not sure if functional or just visual

(video shows duplication with currently playing song, can happen with not playing one as well)

seems like these effects only happen in cases where other songs do not dynamically move when rearranging queue... another symptom?

Aware of this. The issue is that ExoPlayer doesn't correctly update the shuffle order when items are moved, so I have to hack around it in really messy ways instead. The current way works fine if you do simple slow moves, but breaks if you are too fast. I need to make a patch to fix this, which is risky since ExoPlayer's internal queueing is quite complicated and easy to break.
