This was added, does it make a difference? In general there seems to be a whole
lot of cruft in this CSS, can you tried to minimize it to just the stuff that is
actually needed? Like box-sizing:border-box just below here doesn't seem to make
sense, and such is the case every 5-10 lines in this file I think.

de-cruft is still pending, probably in PS20.

The amount of whitespace around the mute button looks really excessive, and was
pointed out by some people I showed the new controls to internally. It makes it
a bit non-obvious that the second slider is related to the volume button at all.
Does this match what was intended in the mockups? I'm no designer, but something
closer to the amount of space between the play button and the duration text
would seem better.

[liberato (no reviews please), 2015/07/09 12:10:56]

i've forwarded this feedback to the design team.  thanks.

[liberato (no reviews please), 2015/07/14 22:10:36]

the new whitespace is from the style guide, and is intended.
