Take it From the Top

So, my friend Caitlin lent me her Paramore CD about a year ago. When I took it, I was thinking, "Paramore... Where have I heard of them before?" But I just couldn't think of it. Then, as I listened to it, "Misery Business" started. And I was like "I know this song!"
Turns out I had heard it a long time before on the radio, when it was a new single, and then had simply forgotten about it.
