Maybe users should be prompted to just remove all actions from the
playlist when they shuffle, since the whole point here is to schedule
actions to run based on upcoming songs, which you can’t do once it’s
randomized.

That would work too, but I’d want some visual indicator that a track
has actions associated with it. I don’t like the idea of invisible
actions in my playlist.

Thanks, that’s really helpful! I’m not sure when I’ll find time to
write this (especially since I’m preoccupied with Emacs bankruptcy at
the moment), but I’m definitely motivated to find an easy way to queue
actions based on my emms playlist. I’ll be back with more questions
and/or updates.

Thanks,
