6. Barbra Streisand
The queen of musicals is known in almost every country of the world — perhaps that’s the reason why she has sold over 150 million sales. Gaining fame in the 60s, Streisand has a whopping 80 albums under her belt, 11 of which have been chart-toppers. She has 52 gold works, 31 platinum albums, and she’s officially the most certified female artist in the US.
