 ### Tell me more!
 
 I wanted an easy way to grab the songs present in my library so I can download it & use it offline. [spotify_to_mp3](https://github.com/frosas/spotify-to-mp3) worked well but it relied on grooveshark, which unfortunately is no more. So I wrote this script which mimics that library, but instead of downloading from grooveshark, it searches YouTube and downloads the song using [youtube-dl](https://rg3.github.io/youtube-dl/).
