LGTM, the only thing we need to keep in mind is how to handle small screens. I think this was initially the reason why the icon was missing. However, I think we also "lost" many devices with very small displays as we dropped KitKat support. I am not sure whether the whole topic is an issue any more, but at least something we need to think about for a moment.

Thank you!

@TobiGr I think the problem does not lie in this specific PR, but rather in the playlist control header which does not scale well to small screens. This PR just adds an icon to one button which in German happens to have more text than other buttons, but for other languages it might be different.
