Honestly, when I was watching some back episodes of Grey's Anatomy I knew the voice in this song was familiar.
I didn't realize it was Fun. of "We Are Young" fame. I also didn't realize they're of the Fueled by Ramen persuasion - which means label-wise, they're in the company of some of my favorites, like Panic! At the Disco, Fall Out Boy, and Paramore.
At any rate, I love the message in this song - of course some of that might be attributed to the fact that the moment in the Grey's episode it was featured in was the culmination of one of the most emotionally draining episodes in the history of the show...that said, I still found myself humming the chorus for the next three days - and I bet now you will be too.
Yesterday I downloaded the entire "Some Nights" album and I'm thoroughly enjoying it.
