Does it fall on one of Taylor's assistants to hit up Wikipedia every time she goes to a new state and come up with a comprehensive cataloguing of every artist Swift knows from that state that she might want to cover on stage? Or is Taylor herself just that good that she can say to herself "Oh yeah, Arizona? Hm, well, I'll do some Jordin Sparks song nobody knows, and then I'll get Jimmy from Jimmy Eat World to duet with me on 'The Middle' and then maybe I'll close it out with some Michelle Branch. Hey, did you guys pick up my lavender dress from the cleaners yet?"

Either way, the end product is Taylor pulling off a trio of covers over Saturday's concert in Tempe, Arizona, most notably the "Middle" featuring Ms. Swift rocking on guitar with Jim Adkins (who she introduces as "someone who has written songs that have gotten me through some of the toughest times in my life"). Check 'em out below, and remember—it's not where you're from, it's where you're at.
