1. Please, make the background color of the My Collection and Browse pages the same as the Now Playing page. It's jarring on my eyes to go from the calm blue to a stark white, not to mention inconsistent.
2. Maybe try matching the background of the Now Playing page to the album cover. I've seen this elsewhere and I like the effect. Also, the ability to toggle this on and off. Some people like consistency, others like a little change.
3. The ability to sort My Collection by Last Played, Times Played, Mood, Genre, and Name would be very helpful.
4. More than anything, I wish the Browse page would remember the items I click most and move them to the top. It's annoying to constantly click thru multiple layers to find stations I wish to listen to. Additionally, the ability to reorder categories (Featured Playlists, Browse Genres, etc.) to the ones I search most and the ability to sort within categories would be exceedingly useful.
