Party In The U.S.A.

This is the lead single from Miley Cyrus' first ever EP Time of Our Lives. The EP was sold exclusively at American Wal-Mart stores in conjunction with the teenage singer's Max Azria clothing line.

The song was scheduled to make its radio debut on August 4, 2009. However, due to an illegal leak of a demo version, it was released early on July 29 for airplay. The song's producers, Katy Perry and Kelly Clarkson collaborators Dr. Luke and Claude Kelly, broke the news to Miley about the leak. The teenage singer expressed irritation but seemed more concerned about the response of the audience to the earlier than expected release of the song. She tweeted to blogger and TV personality Perez Hilton: "How did my friggen song get leaked??? Whatevs. Do you likey?"

The breezy summertime pop anthem features semi-autobiographical lyrics concerning Miley's move from Tennessee to Los Angeles.
