Two real failures from the first hour of round 45, both fixed by treating
the file itself as evidence.
"B. Clem - Zuuso [1025657891]" fingerprinted fine and matched nothing.
Checked before building: AcoustID returns zero results, a MusicBrainz text
search for "Zuuso" returns zero, iTunes returns zero. The track is in no
metadata service on earth, so no smarter lookup could have answered it —
but its filename said exactly what it was. New filename_tags.py reads that,
validated against all 474 files in the untagged folder rather than invented
examples: it strips yt-dlp ids, drops "(Official Video)" noise, splits
Artist - Title, reads a leading 1-04, and falls back to the iTunes tree.
It is careful about what it removes — an 11-char trailing token counts as a
YouTube id only if it carries a digit, an underscore or flipping case, or
"Cold Draft-Underground" loses a word, and a hyphen only splits when it has
spaces around it so Jay-Z survives.
A guess says it is one: candidates carry a source, and the dialog quotes a
confidence only for real fingerprint matches.
The file now ranks lookup results too, which fixes the Alhambra case: token
overlap (words double, bare numbers single), a duration bucket against the
recording lengths AcoustID returns, and a filename year that predates what
the database knows. Live also stops counting as a demerit — it was lumped in
with Compilation and buried a live album for a file whose name said "Live At
The Alhambra". That track now proposes the right album with year 1961
instead of a compilation with 2002.
The year genuinely needed the filename: MusicBrainz's own first-release-date
for "Ahmad Jamal's Alhambra" is 2002, because its three original 1961
pressings are stored undated. The obvious fix of a second MusicBrainz call
returns the same wrong answer.
Not done on purpose: trav rejected "never propose a shorter title" —
truncating is wanted, since the garbage is usually the part being dropped.
