Media Center saves statistics about the number of times files have been played or skipped in special Library Fields called [Number Plays] and [Skip Count]. It also stores a record of the last time each file was played or skipped in corresponding [Last Played] and [Last Skipped] fields.
The logic used to determine if a file was Played or Skipped is relatively simple:
- [Skip Count] is incremented if: (a) playback of a particular file is started, and (b) playback is stopped (via any means, next track, stop, playing something else, etc) before the playhead reaches 50% in the file (for Audio files) and ~90% (for video files).
- [Number Plays] is incremented if: (a) playback of a particular file is started, and (b) playback continues through the point where it will no longer count as a skip.
You don't have to actually play through the files to see this effect. You can manually drag the playhead and watch the [Number Plays] and [Skip Count] fields change after playback is stopped, depending on where the playhead was when you stopped.
Whenever either [Number Plays] or [Skip Count] is incremented, the current date and time is stored in the [Last Played] or [Last Skipped] fields respectively.
