Known for her youthful boundary-stretching performances and lifestyle, Miley Cyrus has evolved from a teen pop star to a polished singer across several genres. She's Billboard's ninth greatest female artist of all time, and has given millions of her earnings to charities, from HIV/AIDs research,to PETA, to LGBTQ youth support programs and more (but of course: she's Dolly Parton's goddaughter). Cyrus has supported many progressive causes and candidates, too, including Black Lives Matter, President Obama and Hillary Clinton. Her newly-released single, the candid, introspective and beautifully sung "Used To Be Young," has been lauded by a variety of stars from Adele to Diane Keaton for its powerful narrative and her tearful raw emotion, sung in her trademark slightly raspy voice. Enjoy.
