Thanks for the tips. I also use folder mode, and my playlists are file-based playlists sync'd over from iTunes. File-based playlists seem to be pretty clunky in Poweramp. It often forgets where in the playlist it last was, and scrolling through a file-based playlist is pretty sluggish. So what I do now is select a file-based playlist, do a random sort on it, then Enqueue it. Now I can play the Queue with shuffle off, and Poweramp can remember its place in the queue from session to session. I can also re-shuffle the Queue if I want to hear some songs already played, repeated.
