Donna Summer, the legendary disco diva behind such dancefloor classics as "I Feel Love," "Last Dance" and "She Works Hard for the Money," has died. Summer had been battling with cancer, and TMZ reports that she passed away this morning in Florida. Summer is survived by her husband, musician Bruce Sudano, and two adult-age daughters, Brooklyn and Amanda. She was 63 years old.

Summer was the most successful solo artist of the disco era, charting four #1 singles and ten other top tens—most in the late '70s with producer Giorgio Moroder as her collaborator, though she remained popular throughout the 1980s as well and was an early presence on MTV, one of the few black artists the channel played before Michael Jackson's video breakthrough.

Her career was important and influential enough that Summer was one of our ten nominees for the inaugural class of the Popdust Hall of Fame. She was a great artist and will be missed.
