Sunnify
Spotify downloader application + CLI to download playlists
...The application retrieves Spotify metadata and matches recordings from YouTube using yt-dlp. Audio can be saved in MP3, M4A, Opus, FLAC, or WAV formats with selectable encoding quality. Downloaded files include embedded metadata, track numbers, and individual cover artwork. Parallel downloading and resumable sessions simplify managing large playlists. Users can customize filenames and organize downloads into separate folders. Sunnify also includes a graphical interface, a headless command-line tool for automation, and bundled FFmpeg without requiring a Spotify account.
