It's not so much an interview, but more of a complete 1989 love in where they insist the other person's version is better. Kind of. Highlights include Taylor Swift's epic hair flick, Ryan never removing his glasses, and Siri being in typically snarky form. They also talk 'dream lyrics' (as in lyrics syphoned from dreams), inadvertent notebooks/phone notepads (or "word blurbs"), and overuse of the word 'like'. 

Lastly they divulge what recharges their creative batteries. For one, it's The Smiths, for the other, it's John Hughes movies...
