The death of Donna Summer on Thursday (May 17) at age 63 after a long battle with cancer has many reflecting on the impact the disco legend had on music.

While many may not realize it, Summer is the foremother of, well, just about every pop song on the radio today. Her iconic 1977 anthem "I Feel Love," which peaked at #6 on the Billboard singles chart (one of 14 top 10 hits), was the first mainstream song to be produced using an entirely synthesized backing track. Until then, most disco recordings had been backed by acoustic orchestras, and the reception to the song revolutionized music.

"One day in Berlin, [Brian] Eno came running in and said, 'I have heard the sound of the future,' " David Bowie famously wrote in the liner notes to Sound and Vision. "He puts on 'I Feel Love,' by Donna Summer. ... He said, 'This is it, look no further. This single is going to change the sound of club music for the next 15 years.' Which was more or less right."

Indeed, imagine the music of Lady Gaga, Britney Spears, Rihanna, Katy Perry and countless others minus their ubiquitous glittering synths. You can't. Without what was at the time a risky and bold move, modern dance music might not exist as it does today.

Summer's impact on music is so vast it's nearly incalculable, but in memory of the disco diva, we're looking back on some of the ways her music has survived through the years, has been brought to life by other artists and how many of music's biggest names counted themselves as fans of the Queen of Disco.

» The refrain from Summer's 17-minute 1975 breakthrough "Love to Love You Baby" is sampled on Beyoncé's hit "Naughty Girl" from her debut solo album Dangerously in Love.

» For the elaborate opening sequence of Madonna's 2006 Confessions Tour, a 2-ton, $4 million disco ball was lowered onto the stage at the end of the runway and then opened to reveal the star, who started into her own synth-heavy "Future Lovers" before the song dissolved seamlessly into Summer's "I Feel Love."

» "Hot Stuff" and "MacArthur Park" are go-to songs for reality singing contestants looking to prove their range — Summer was a mezzo-soprano with a powerhouse delivery — while keeping things upbeat. Both songs have been performed on "The X Factor" and "American Idol."

» Bruce Springsteen was a big Summer fan and wrote two songs for her. The first one, "Cover Me," he ultimately recorded for his own Born to Run, but Summer recorded the second, "Protection," and Springsteen and the E Street Band supplied the track. The pair also recorded "Protection" as a duet, though it was never released.

» Summer is easily one of the most sampled artists in the history of music. "I Feel Love" has been sampled by some of the biggest artists in dance, from Madonna and Britney Spears to David Guetta and Moby, and covered by artists as diverse as the Red Hot Chili Peppers, Kylie Minogue and Blondie.

I think people forget how much Donna influenced today's artists and the music scene in general. She will be missed
