metadata: show the playing album tint on the home screenshot

Tint the home screen with the artwork theme the app derives from the playing
album, so the subtracks logo and accents pick up a vivid colour (The Knife -
Shaking The Habitual) instead of the default scheme. Switch the now-playing and
album screens to The Polish Ambassador - Future, Sex, Computers, and search for
"chill" so the result grid shows the Chillhop Essentials covers.
