This is a 'marginal' accomplishment for someone who is "supposedly" one of the "best singers ever." 35 yrs into Barbra Streisand's career she landed 2 - #1 Billboard 200 Albums - one that was Broadway showtunes and the other was spiritual songs. Both beat out rock/r&b artists and sold 2 and 3 million respectively. Streisand went on to have an additional #1 Billboard 200 -- 45 years into her career and then 2 more 55 yrs into her career. Streisand is and was the GOAT.
