streamrip is a CLI application that downloads music tracks, albums, playlists, and artist discographies from Qobuz, Tidal, Deezer, and SoundCloud. It operates as an async pipeline: user input (URLs, IDs, or search queries) is parsed into pending items, resolved into metadata-rich media objects, and then concurrently downloaded with rate limiting. The system handles audio conversion (via ffmpeg), metadata tagging (via mutagen), artwork embedding, and maintains a SQLite database to avoid re-downloading known tracks. The codebase is modular with separate client classes for each streaming service, media abstraction layers, and a config system based on TOML. It uses rich for console output and progress bars.
