- Extracted common JSON parsing helpers into internal/jsonutil
- Removed duplicated helper functions from provider packages
- Removed dead code in internal/app/app.go and downloader.go
- Replaced deprecated strings.Title with jsonutil.TitleCase
- Added graceful shutdown with signal handling in main.go
- Split monolithic cmd/rip/main.go into args.go, helpers.go, lastfm.go, search.go
Replace Deezer yt-dlp usage with native ARL session + media.get_url resolution, add BF_CBC_STRIPE decryption in downloader, and wire cipher-aware Deezer downloads through the main rip pipeline. Includes validation hardening and metadata/source-id improvements used by tagging flows.
Queue resolved last.fm tracks as playlist media to preserve playlist semantics, and add a robust mirror-based parser fallback for last.fm temporary unavailable responses while keeping track order and duplicates.
Improve Deezer full-quality mode behavior by returning explicit errors when yt-dlp mode fails with fallback disabled, parse structured API errors, and correctly map explicit_lyrics booleans into explicit tags.
Use album artist overrides during album ripping so compilation-style tracks do not change album performer tags, and add safer disc-number fallbacks for metadata/path generation when providers omit disc fields.
This brings the Go CLI closer to upstream behavior with global flag handling and clearer resolve failures, while adding Tidal video downloads plus initial Deezer and SoundCloud no-account flows for broader end-to-end coverage.
Write replaygain gain and peak tags from provider-specific metadata fields, then apply tagging across supported output containers with graceful cover-art fallback so non-FLAC downloads retain metadata.
Make download dedupe source-specific to prevent cross-provider ID collisions. Also correct non-remaster filtering, avoid FLAC tagging on non-FLAC files, and use album IDs for singles folder templating.
