Why?

We recognized that while v3 was simplified and easy to use, some users wanted further functionality to use spotDL the way they want. v4 has been designed from the ground up to retain the simple and easy to use interface, but also provide these advanced options for customizability.

Key Features

You've asked and we've provided! Some of the most asked for features:

• Sync Mode Keep your local files up to date with your Spotify playlists. Use a sync file to track changes (deletions or additions)
• Configuration File Annoyed about typing your desired output path every time you run spotDL? v4 brings back the config file - Look at \.spotdl\config.json in your user Folder
• Audio and Lyric Providers Customize where audio and lyrics come from. AZLyrics, musixmatch or Genius
• FFmpeg Download We know lots of people had issues downloading FFmpeg, so now spotDL can do it for you!
• API It is now easier than ever to use spotDL in your own code!
• Documentation & Tests Code is 100% documented and tests over 70% coverage!
