Time left and finished go by the length the player measured

A feed can be minutes out: ReThinking's gave 41:23 for a 43:48 file,
which read 0:08 left with 2:33 to play. The player's length is kept in
entry_state beside the position, per listener, where no scan can put
the feed's figure back, and preferred to the feed's.
