Why work entities are not created automatically for every recording the same way release group created for release? Auto-created works would contain performance (recordings) relation to manually added recording.
It is common for band to create work and then record it for an album. Sometimes they create new recording of it some years later.
Should I add works for all recordings I’m adding?
There’s also related practical issue: say I found two recordings of the same song by a band (a band probably doesn’t exists by now). Recordings are clearly differently arranged. I may or may not discover any additional info in future. For such files I manually picking tags after metadata import in Picard removing all release related tags: MBID’s, album, total discs, total tracks.
With “work MBID” available I would have a way to link such file to (community) managed metadata.
