My situation is the following:
- At some point I got a large database of music files, in mp3 format.
- I added album covers using MP3tag automatically.
- That software changed the timestamps of all my music files to some new values.
- I still had the pre-changed files, the files with the original timestamps.
- Now, a dilemma – based on 1,000 files with old/new timestamps, how can I transfer the old timestamps to new timestamps?
The solution proved a bit difficult. I detail it, below.
