Wow! 70?? Time does fly, doesn't it?
She and her group Blondie had some "GoaT" hits back in the day:
"Heart of Glass" (1979)
"One Way or Another" (1979)
"Call Me" (from 'American Gigolo'; 1980)

"The Tide Is High" (1980)
By the way, I seem to remember that when they had their first Number One hit, some people initially believed they named the group after the classic comic strip character "Blondie", or that that was Ms. Harry's actual name (because of her blonde hair). Anyhoo, HAPPY BIRTHDAY, Ms. Harry, and thank you for all the cool tunes!
