All Too Well by Taylor Swift. I bought the CD at Target, put it in, was jamming out to all the singles that were already released and I got to Track 5. And Track 5, that's where it all changed. Man, that song just, it hits so hard through so many curveballs, fastballs, the whole thing. And I was like, this song is gonna be like one of the greatest songs of all time from here. And I think it is still. But nobody else believed me at the time either so that was interesting.
