I am using MP3tag with a file server on a local network.
Updating tags is slow... About 10 to 15 minutes for 40 songs.
I suggest creating a mode where updates are made in 2 steps:
- the user edits everything he wants on a local copy of the tags (same computer)
- when all edits are made, the local tags are cloned to the real files (remote computer)
This way the user can go away while the files are updated.
Thanks for reading !
