The Best of Both Worlds (song)

"The Best of Both Worlds" is a song by fictional character Hannah Montana, recorded by American singer and actress Miley Cyrus for the soundtrack of the Disney Channel series Hannah Montana and used as its theme song. It was released by Walt Disney Records on March 28, 2006 as the lead single from the soundtrack album. A live version is available on Hannah Montana & Miley Cyrus: Best of Both Worlds Concert (2008), a karaoke version is included in the soundtrack's karaoke series (2008), and the 2009 Movie Mix is featured on Hannah Montana: The Movie soundtrack (2009). The song has elements of bubblegum pop and pop rock. Lyrically, it is a showcase of the double life lived by Miley Stewart.

"The Best of Both Worlds" is considered to be one of Cyrus' signature songs, introducing her to the music industry. The song received generally positive reviews; critics noted that the song was written well despite its "weird" concept. "The Best of Both Worlds" reached number 92 on the Billboard Hot 100, making the song only one of two television themes of the decade (the other being "Leave It All to Me" by Miranda Cosgrove) to chart on the Hot 100, and achieved some commercial success internationally. The song reached its highest international chart peak position on the Irish Singles Chart, at number seventeen. A promotional music video for the song was taken from a recording of a concert performance. Cyrus promoted the song by performing it at several venues, including her performances as the opening act for The Cheetah Girls' 2006 The Party's Just Begun Tour and as the closing number on her own 2007 Best of Both Worlds Tour. Cyrus' performances of the song on tour were as herself, but when she performed the song on television, it was in character as Hannah Montana.
