When the fingerprint score is >=0.95 but title/artist don't match
(e.g. English expected vs Japanese returned), SKIP instead of FAIL.
A 95%+ fingerprint means the audio IS the correct recording — the
metadata mismatch is just a language/script difference, not a wrong
file. Prevents Japanese, Chinese, Korean, and other non-Latin tracks
from being falsely quarantined.
Happy path unchanged — matching title/artist still returns PASS at
the earlier check before this code is reached.
AcoustID sometimes returns featuring info in square brackets like [W/ Barnes Blvd.] instead of parentheses. The normalizer only stripped parenthetical featuring tags, so these tracks failed verification and got quarantined despite being correct. Now strips [W/ ...], [with ...], [feat. ...], and [ft. ...] bracket patterns too.
Expand track title normalization and refine album grouping logic.
- core/acoustid_verification.py: Broadened the parenthetical-suffix regex to strip year-based remasters and additional variants (e.g. "2025 Remaster", "single edit", "album edit") while still removing common extras like (Live), (Deluxe), (Radio Edit), and featuring tags.
- web_server.py: Restrict the smart album grouping to only run for singles/auto-detected albums; explicit album downloads now preserve the original Spotify album name to avoid mangling names (e.g. reworked/remastered vs deluxe). Added explicit logging for both smart grouping and skipped grouping paths. The verification post-processing worker now checks an is_album_download flag in context and skips re-grouping when true, with fallback logging on errors.
These changes prevent unintended renaming of explicit album downloads and improve normalization of common title suffixes.
Add optional post-download audio fingerprint verification using AcoustID.
Downloads are verified against expected track/artist using fuzzy string
matching on AcoustID results. Mismatched files are quarantined and
automatically added to the wishlist for retry.
