Kesha

Singer and songwriter Kesha dominated the charts in 2009 with "Tik Tok," a party-till-you-drop anthem that blended pop lyrics, hip-hop delivery, and electronic beats. Kesha turned the mega-hit into her signature sound, propelled by similar hits off her debut album, "Animal" (2010). The vocalist also turned in decent acting performances, often mocking her party-girl image, in hilarious short films for the website Funnyordie.com that went viral. A hybrid of 1980s-era Beastie Boys and '90s-era Madonna, Kesha's irresistible hooks, coupled with her carefree attitude, entertained millions and firmly planted her career as a reputable pop star. Unfortunately, her career was derailed by an extensive legal battle with her label, Sony Records, focusing on an October 2014 lawsuit charging songwriter/producer Dr. Luke (Lukasz Gottwald) with sexual assault and battery, sexual harassment, and emotional abuse; although the lawsuit was rejected in April 2016, Kesha's ongoing outspokenness on the topic garnered her a large contingent of fans who supported the singer in her quest to regain control of her career.
