Media Files Update and Track Meta Data

[serendip1959]

When the database is updated the media file is updated, even if the changes are not stored in tags (for example last played and play count). This causes the media to be re-synced back to the device even though the media is already on the device. I noticed when syncing my iPhone that the tracks updated with play count and last played were being synced back onto the device. Upon checking, the file modified date is being changed.

I noticed, but can't say when it occurred, that track metadata (rating and play count) became changed affecting about 5% of all tracks. Tracks with 5* became 3*, some 2* became 4*. Tracks with a correct play count of <10 acquired a play count of 70+. As I have only just noticed this I can't attribute it to an event.

Which build? I'm not seeing this.

Note that you may also have Lyrics or Artwork lookup happening which is a tag change.
