Regarding Play Now button (red-circled):
- Upon a click, it adds tracks to now playing list always in alphabetical album title order regardless of the currently selected album sort. From the screenshot above, it should add and play "Little Voice" album first.
- The button could toggle to play and stop icon, rather than keep showing play icon, indicating whether the selected artist is playing. Also the button could have a slightly different color/shade from artist name/album title.
