What does heart icon next to album image means? I couldn't find documentation for it anywhere. I guess it's favorite button, but I cannot find play favorite songs either.
The heart is a like/dislike option for a song. If selected, it means you like the song. This like feature is very useful in zune software. It gives you the ability to create an Auto-playlist for liked songs.
NOTE:- you can't do this on phone; as creating, editing and deleting playlist is restricted to zune software only
