PlaylistDownloader

PlaylistDownloader is a project to download audio files (songs, etc.) from multiple providers with a simple Python extension of existing libraries. The project extends the following features:

Auto-detects the provider of the required audio file
Provides a REST API that parses a list of playlists or songs in a text file

This program is essentially a wrapper for youtube-dl, which already offers most of these features.

PlaylistDownloader downloads playlists (from Spotify, YouTube, etc.) by finding and downloading the MP3 files of the music videos on YouTube.
