Replace JOOX playlist tracks automatically on a Last.fm playlist
JOOX is a freemium service providing most of its songs for free while some songs are only available for premium users, offered via paid subscriptions or by doing the different tasks offered.
Using a music recommender system called Audioscrobbler, Last.fm builds a detailed profile of each user's musical taste by recording details of the tracks the user listens to.
Soundiiz is the most complete online tool to manage your music library between multiple services. It offers a simple way to import and export playlists and favorites tracks, artists, and albums.
