I think Bee-liever was referring to the differences in vertical line spacing here:
correct
yes that is an intentional extra spacing for Now Playing and Music Explorer
OK I can understand spacing the Now Playing further away by hiccup's reasoning.
But wouldn't Music Explorer either be 16px down (as a conceptually different entity)
or only 9px down if it's to be grouped with Now Playing?
Not the odd 11px spacing it currently has.
