Miley Cyrus' 'Wrecking Ball' was her first number-one hit on the Billboard Hot 100. While the music video (directed by Terry Richardson) became a massive viral sensation for its provocative imagery, the song itself was praised for Cyrus’s raw, powerhouse vocal performance. The track was co-written by MoZella and Sacha Skarbek, who also co-wrote James Blunt's 'You're Beautiful.' The song’s lyrics deal with the collapse of a relationship, which many fans connected to Cyrus's real-life breakup with Liam Hemsworth at the time. The video broke the Vevo record for most views in 24 hours (19 million) and won Video of the Year at the MTV VMAs. It marked Cyrus's definitive transition from Disney star to a provocative, serious artist in the pop landscape.
