Comment 1 for bug 1862709

This has already been discussed:
https://bugs.launchpad.net/mixxx/+bug/1791504

Please consider:
- Hashes of files need to be updated after metadata has been modified
- Files may be modified at any time outside the control of Mixxx
- Time stamps of files may not change if their metadata or contents have changed
- Files could be moved and modified at the same time, e.g. consider https://beets.io/

Content-based, location-invariant identification of files would indeed be nice. But any approach must cover all possible use cases. If you have ideas how to extend the database schema, library scanner tasks, or the track relocation algorithm please share them.
