The iTunes faithful may remember that iTunes 12.4 removed the "Reset Plays" option. This command would zero the Plays and Skips of a track.
AppleScript to the rescue: I posted a script, Reset Plays, that replicated this feature and additionally deleted the Last Played Date and Last Skipped Date, turned off "Remember Playback Position", and set the played property to false; essentially, rendering a track as "never played".
Whether due to user clamor or by design, the "Reset Plays" feature was restored in iTunes 12.4.1 and I figured the script was obsolete.
Today, I got around to trying iTunes' native "Reset Plays" in v12.4.3 (it is not something I would normally use at all). While the Plays and Skips are set to zero as expected, surprisingly, the Last Played Date and Last Skipped Date remain; such that a Smart Playlist filtering by the date a track was last played (or skipped) will not realise that these "reset" tracks were supposed to appear as never played.
So, Reset Plays may actually still be useful.
