This looks like a bug for me, here the symptoms.
1. Out of the blue the entire favorites folder disappeared in my iPhone.
2. I'm able to access the favorites folder in my computer, also i can play it and hear it at iphone(!!!!) but i can't see the music in the favorites list.
3. Bonus: I have to add all the songs from the favorites AGAIN because it shows it's not on the on my folder (iphone), that i previously selected to play on my desktop favorites folder (!!!!!!!!)
I'm premium user, please fix it, i want my musics back.
