Taylor Swift made a rather large statement about her status in the music business during 2011 by simply placing a request. Entranced by Nicki Minaj's hit single "Super Bass," she invited Minaj to come out to the Staples Center in Los Angeles and perform the song in a surprise appearance during Swift's concert in August. In the aftermath, Justin Bieber asked if he could do a guest spot with Swift. In short order, the singer/songwriter was lining up musicians in many of the major markets to add a little local flavor to the night: Jason Mraz in Los Angeles; Usher and T.I. in Atlanta; Shawn Colvin in Austin; Jim Adkins of Jimmy Eat World in Phoenix; Ronnie Dunn, Tim McGraw, Kenny Chesney and Paramore's Hayley Williams in Nashville; and Selena Gomez and James Taylor at Madison Square Garden in New York, as her 2011 tour concluded.
