I've been listening to them since about 2007 or 2008, and they've always been the band I turn to when I have a horrible day and need to just relax. I got to see them live for the first time in April for my birthday (they usually just tour on the West coast) and I had such an amazing time. My bestfriend who lives in Florida saw them a couple dates before mine, and she had them autograph one of their albums saying "Happy B-day, Amy" and gave it to me. I cried.
