Agnetha Fältskog — Age 71

Agnetha Fältskog was born to be a musician. The Swedish singer-songwriter wrote Två små troll, her first song, at only six years old. A decade later, she would join the Bernt Enghardts band before releasing 1967’s Jag var så kär, her first single.

The following year, her big break came in Sweden after her self-titled album debuted in 1968. She then topped that achievement by reaching global stardom as a part of ABBA. Since 2018, Fältskog and fellow ABBA member Frida Lyngstad have been working on a reunion project set to be unveiled by 2022.
