In April 2008, Cyrus released her first solo album, Breakout (2008), which experienced international success and she was included in Time magazine's 2008 Top 100. She began her foray into films by providing the voice of "Penny" in the animated film Bolt (2008) and by reprising the role of Miley in Hannah Montana: The Movie (2009). Bolt's theme song, "I Thought I Lost You", earned her a nomination for the Golden Globe Award for Best Original Song. Hannah Montana: The Movie' soundtrack introduced her to new audiences within country and adult contemporary markets.
She began to cultivate an adult image in 2009 with the release of The Time of Our Lives (2009), an extended play which presented a more mainstream pop sound, and by filming The Last Song (2010), a coming-of-age drama film. The former included Cyrus's best-selling single, "Party in the U.S.A." (2009). Cyrus ranked number twenty-nine on Forbes' 2009 Celebrity 100. An upcoming studio album titled Can't Be Tamed will be released in 2010 and presents a new dance-pop sound. The music video and lyrics of the album's lead single, "Can't Be Tamed", portrays a more sexualized image for the entertainer. Cyrus has stated that she intends to focus on acting rather than singing in the future. pop female vocalists Disney dance guilty pleasure
