I really enjoy this program and the fact that you can create music playlists for free but I'm not too happy that you can only find your friends playlists if you have them added as a friend on facebook. Why does it have to be linked to facebook? Urgh. So I have to add everyone to facebook. Then I can find their playlist. What a pain.
Overall if you haven't used this program yet give it a shot! Its free and amazing! https://www.spotify.com/us/
