I first got into buying music when I was 8, with 7" 45-rpm singles. Three of my first five were Donna Summer singles. I've picked up a few of her other hits along the way.
She was one of the quintessential voices of the disco generation, and beyond. I have her Grammy-winning later single "Carry On," in which she reunited with her "I Feel Love" co-creator Giorgio Moroder, and her voice in it is as smooth as when she started.
Tonight when I get home, I'm going to have to fire up the ol' synths and trigger that I Feel Love bassline in tribute...
EDIT: In response to ericrwalker, here are a few of Donna's hit songs:
Love To Love You Baby
I Feel Love
Macarthur Park
Last Dance
On The Radio
Hot Stuff
Dim All The Lights
The Wanderer
She Works Hard For The Money
This Time I Know It's For Real
Carry On
And here are some disco songs sometimes incorrectly attributed to her:
I Will Survive (Gloria Gaynor)
Don't Leave Me This Way (Thelma Houston)
Knock On Wood (Amii Stewart)
