Taylor Swift with her guitar is classic Taylor Swift all the way, so yes, of course she opens her hosting gig with a song titled, well, "Monologue Song (La La La)." We hear it all — from her love for Winter smells to her messy breakup with Joe (Jonas not Alwyn). It's hilarious in a jokingly passive-aggressive, proto-Reputation kind of way, and we love to see Tay be able to "shake it off."
