Now just go below the break for the answers, along with some solver comments!

The letters in the brown squares spell out HYBRID THEORY

Random fact: "Hybrid Theory" was also Linkin Park's original name!

Solver Eric Maddy noticed a huge mistake I made in the original posting of this puzzle: "um, [the Wholes] were in the same order as the Centers" needless to say, as soon as I saw his email, I fixed that problem as soon as possible!

Looks like that puzzle wasn't the only one "Squeezed in the Middle"...

Solver Yossi Fendel interpreted HYBRID THEORY "As in "I'll bet that Prius is expensive..."

Solver Tyler Hinman "Do[es]n't think I'll enter the contest; got too many puzzles as it is. I guess that means, in the end, it doesn't even matter."
