spotdl/spotify-downloader

spotDL is a command-line tool that finds songs from your Spotify playlists on YouTube and downloads them to your computer as audio files, complete with album art, song lyrics, and metadata (artist name, album, track number, etc.) automatically embedded. The idea is that Spotify itself doesn't let you download music for offline listening outside of its app, so spotDL bridges that gap by matching Spotify's metadata with the corresponding YouTube audio. It works by looking up songs from a Spotify URL, finding the best-matching audio on YouTube, downloading the highest available quality (up to 128 kbps normally, or 256 kbps for YouTube Music Premium users), and then tagging the file with all the metadata from Spotify. FFmpeg, a free video and audio processing tool, is required for the audio conversion step. The tool supports several operations: downloading individual songs or whole playlists, syncing a local folder so it stays up-to-date with a playlist (new songs are downloaded, removed songs are deleted), saving metadata without downloading, and more. It can be run as a simple command, as a Python package, via Docker, or through a basic web interface. You would use spotDL if you want local copies of your Spotify music with proper metadata for use in media players, DJs sets, or offline listening. It is a Python tool installable via pip and runs on Windows, macOS, and Linux. Note: the project itself states that users are responsible for the legal implications of their downloads.
