Taylor Swift covers Eminem's 'Lose Yourself, says 'Yo!' very well

Taylor Swift, who’s always kinda shocked about something, now takes pride in causing her fans to make the Surprised Face.
And she’s been extremely successful at achieving that during her Speak Now tour by covering hometown artists from each stop.
In Toronto, she played a Canadian medley that included Justin Bieber’s “Baby,” Alanis Morissette’s “You Learn,” and Tal Bachman’s “She’s So High” (though—you guys!—she totally wasn’t).
In Newark, New Jersey, during a set that we reviewed in EW, it was Bon Jovi’s “Livin’ On a Prayer” and Bruce Springsteen’s “Dancing in the Dark.” And just last Wednesday, she performed Eminem’s “Lose Yourself” for Grand Rapids, Michigan, segueing into a cover of Uncle Kracker’s “Smile.”
We don’t know what we like more about this clip, that Taylor’s so gratified by shouting “Yo!” or that billions of preteen girls know every single word to an Uncle Kracker song. Watch Swift pay tribute to Eminem’s mom’s spaghetti after the jump.
