() struts in on a massive drum line and crunching, processed guitars, gets amplified by a four-piece horn section, then falls away to a simple, somber piano line. It's sexual one minute, heartbreaking the next — the perfect accompaniment for Wentz's tale of infidelity and deception. Swagger is a great way to describe it, because on the song, he's lyrically adopting a character that has swagger, so I wanted the music to have that swagger. The verse is so confident and funky and forward because the lyric is so full of itself. And then everything stops, and there's a piano breakdown, and it's very melancholy and sad and theatrical, and the lyric shifts to the doubt that's behind all that arrogance. And ultimately, I wanted the music — in conjunction with the lyric — to express that arrogance is usually a mask for terrible insecurity. -- vocalist/composer/guitarist Patrick Stump on the composition of "Headfirst Slide into Cooperstown on a Bad Bet."
