Freddie Mercury, 45 Years Old
Queen frontman Freddie Mercury tragically passed due to complications from AIDS when he was 45 years old. He was relatively private about his illness, and is best known for his theatrical stage presence and falsetto vocal styling. He wrote hits like "Killer Queen," "Don't Stop Me Now," and "Bohemian Rhapsody." The biopic "Bohemian Rhapsody" features actor Rami Malek in Mercury's shoes.
