Asobi Seksu - Citrus
This image has fun with the distorted Japanese type, but gets to the point by incorporating a monochromatic, yellow/orange color scheme to mirror the title of "Citrus"

7. Less Is More -
The xx - xx
The big white "x" on a flat black background says plenty by itself.
8. Negative Space Is Magical -
Deftones - White Pony
Similar to the "less is more" principal as well, this one takes advantage of the vast gray negative space to accentuate the simple white pony.
9. Type Is Both Word and Image -
Strong Arm Steady - In Search of Stoney Jackson
It took me a second to realize there is actually eyes, a nose, and a mouth hidden in that type.
10. Keep Type/Text Friendly -
Grizzly Bear - Friend
An obviously handmade background title, that's easy to read and "friendly."
