Originally co-written by English artist Jessie J for her own use, "Party in the U.S.A." was repurposed for Miley Cyrus to reflect her intimidating move from Nashville to Hollywood. The dance-pop song peaked at Number Two on the Billboard Hot 100, becoming the former Disney star's biggest hit to date. Her performance of "Party" at the 2009 Teen Choice Awards was met with controversy when a scantily clad then-16-year-old Cyrus did a suggestive pole dance. She once described the track, whose accompanying music video riffs off the 1978 film Grease, as "an all-American song … about my roots."
