Feature Request: Store song details by file hash instead of filename

[Aaron Esau]

Right now, if I rename a song to something else, all details associated with that song (e.g. the song analysis) is lost. Details should be stored based on the hash of the file so that I can rename files without losing the analysis.

This has already been discussed:

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.

Mixxx already has the capability to detect renamed files upbto a certain extend. Maybe the original issue that this is broken or does not work as expected.

Can you report step by step want you have done and how Mixxx responds?
Which version of Mixxx are you using on which OS?
