Discovery at its conference, Spotify has advanced a lot of figures about its progress in the music streaming market. Thus, we learned that a billion playlist are now available on the service. In addition, Spotify was proud to announce that 5 million users chose the unlimited plan (ie pay) including 1 million in the U.S. over 20 million in total. The beneficiaries are not left behind, despite the criticism, with more than 500 million returns since the launch of the service is 70% of income.

But the real ads are far more important, and directs the service to sociability. The first announcement is the launch of a new personalized recommendation system for new artists, just like the radios that already existed. Similarly, a new web interface will take place at the end of the year, for better interactivity and clarity. A new collection feature to store your favorite songs, will also be implemented. Additionally, each artist will now have a clean page, with news, his concert dates and even ticket sales!

But this is not all. Spotify announces the launch of the Audio Preview which allows you to discover new music and on his return after Playlist as if nothing had happened. A new tab “subscribe” will also emerged, allowing you to follow friends and artists to get their news, their recommendations, and even listened to their music in real time! A kind of music social network, basically. Spotify is therefore improves greatly, and is modeled on actors who have already proven (Myspace, Twitter) to continue to improve the user experience. We are now waiting to see up close what happens in practice.

Finally, last but not least announces the arrival of Metallica on the service. News that should delight fans of the cult group hairy!
