We have extended the "repeat" button in Audio Player app to support 3 modes:
1. no repeat
2. repeat all (playlist)
3. repeat one file

Currently the icon animates like seen in "after-change.mp4" attached to this issue.
1. arrows icon
2. arrows icon + gray box
3. arrows icon + "1" in it + gray box
Currently there is no animation of the gray box when switching from 2 to 3.

So I would like to know if there are any official design requirement about the animation for this kind of button.

will add an effect like seen in after-change.mp4, but perhaps different.
