A few years ago I was listening to a song on Spotify. I really enjoyed it and wanted to find more with a similar vibe, but it was hard to pin down the genre and the native Spotify reccomendations were useless. So I looked for a way to find other users playlists which contained this song and so would hopefully contain others like it.

I wanted an easy way to grab the songs present in my library so I can download it & use it offline. I no longer use this, but continue to maintain this. spotify-dl doesn't download anything from Spotify. It picks up the metadata from Spotify API and then uses yt-dlp to download the song.
