Repair metadata

Fix album artists, fetch art, year, and genres — in place.

fix repairs your library’s metadata so albums group correctly and show art on the iPod. It writes back to your files in place — never moving or renaming them.

What it does

A three-step native pipeline:

1. Repair album artist — so compilations and multi-artist albums group correctly.
2. MusicBrainz — fetch missing cover art and release year.
3. Last.fm — fetch genres.

All three steps are index-driven (no filesystem walks for already-clean state) and cache both positive and negative results in SQLite, so re-running on an unchanged library does zero network work.

Refreshing

clickwheel fix --refresh-mb        # re-fetch MusicBrainz art/year
clickwheel fix --refresh-genres    # re-fetch Last.fm genres

No external dependencies beyond the base install — fix uses native MusicBrainz/Cover Art Archive + pylast-driven genre lookups.
