^Amy Winehouse's album wasn't released until March 2007 in America (unfortunately), but either way, anything released from Oct. 1, 2006 to Sept. 30, 2007 was eligible to be nominated this year.
I'm so beyond happy for them that you'd think I'd just been nominated myself.
This is great for them, whether they win or not. For the Grammys to acknowledge them is amazing, and now everyone will know who they are. Great for them! If they actually do win, I may just have a small heart attack on February 10th. lol
