When downloader is set to Auto and all configured services (Tidal, Amazon Music, Qobuz) fail, the app can optionally fall back to YouTube via yt-dlp. Changes: - backend/youtube.go: new YouTubeDownloader that auto-installs yt-dlp on first use, searches YouTube (ytsearch5), picks the candidate closest in duration to the Spotify track, downloads best available audio, converts to MP3 320kbps via ffmpeg, and embeds full Spotify metadata + cover art - app.go: add case 'youtube' to DownloadTrack switch - frontend/src/lib/settings.ts: add youtubeFallback boolean setting - frontend/src/types/api.ts: extend DownloadRequest.service with 'youtube' - frontend/src/components/PlatformIcons.tsx: add YouTubeIcon SVG component - frontend/src/components/SettingsPage.tsx: add YouTube Fallback toggle (visible in Auto mode, off by default) - frontend/src/hooks/useDownload.ts: after Tidal/Amazon/Qobuz all fail, attempt YouTube when youtubeFallback setting is enabled (both downloadWithAutoFallback and downloadWithItemID paths) - .github/workflows/build-macos.yml: CI workflow to build macOS DMG (macOS cannot be cross-compiled from Linux)
The bogem/id3v2 library was silently failing to write tags to ffmpeg-converted MP3 files. Switch to an ffmpeg-based second pass (matching the existing M4A approach) which reliably writes ID3 tags and embeds cover art in the same step.

Too bad it's not flac and thus not really scope of this project, spotube (web) linked in the readme does the same, and outputs .mp3 |

Well, I see. But it's still option to get a full release, in case only some tracks are failed to download, which happened to me. Not sure why, but only Amazon works for me (with VPN), and also, on some obscure releases it failed to download 3 out of 7 tracks. |
