PUZZLE #50: Squeezed in the Middle 4 (CONTEST PUZZLE!)

CONTEST!
PUZZLE #50

SQUEEZED IN THE MIDDLE 4

It's my fiftieth puzzle! To celebrate, it's time for another Contest Puzzle! The prize for winning this contest is a signed copy of the December 2015 issue of GAMES Magazine that I got published in! There will only be one winner for this contest, though if at least ten people solve this puzzle, I'll give out a second copy to another winner! If you don't want to enter this contest, you can still solve this puzzle and opt out of the contest. Now with the contest rules out of the way, let's get to the directions of the type of puzzle I made for that issue!

For this puzzle, you're going to sandwich together words (entered in the white rectangles) by surrounding it with a letter on each side, one at the beginning and one at the end, making a new word in the process. Once you're done, the extra letters you've added in the "crust" (the brown squares) will spell out a two-word phrase. In the example above, the words URN, RAT, and OVER become BURNT, IRATE, and GOVERN, and the letters in the brown squares, reading down, spell out BIG TEN. However, to make things trickier, the "Wholes" will be in no particular order, so it's up to you to figure out which one of the "Centers" it matches up with!

Once you've filled out everything, the letters in the brown squares, reading down, will spell out this week's FINAL ANSWER: The name of one of the best-selling albums of the 2000s

CENTERS
1) Washingtons in your wallet
2) Like a tennis ball that didn't land in bounds
3) Serial Experiments _____ (weird anime)
4) "Doc _____" (nickname for a Spider-Man villain)
5) Suffix for "Awe" or "Grue"
6) It "implies can", according to Kant

WHOLES
* Wallaby who's best buds with Heffer and Filburt
* Former Soul Coughing frontman Mike
* Adjective for Abe
* Glucose, to fructose
* Magician and endurance artist David
* They've "Gone Wild" in a Skid Row song

Once you believe you've figured out the FINAL ANSWER, send it to either redhead64@chartermi.net or itsredhead64@gmail.com (though I'm more likely to check the second one) and I'll put your name on a solvers list once I post the answers in about two weeks. You can also use those email addresses to give me some comments and feedback (or get a hint from me in exchange for a "hint star", more details for that are on the sidebar to the right) or send me the answer to last week's puzzle, if you haven't already figured that one out. If you have a printer and want to solve this puzzle on paper, just head below the break for a version you can print out!
