NEW YORK (MainStreet) — Few people would have suspected that Chic's "Le Freak" -- better known as "Freak Out" -- would have a 35-year shelf life, but the disco hit from 1978 was part of a "Grammy Moment" performance by Daft Punk, the techno music titans that swept the music awards this weekend.

The French dance music duo with robo personas topped off their 20-year career by dominating the 56th Grammy awards -- winning five awards, including album and record of the year. It is the first time a dance-oriented album has won a general category honor since 1978's "Saturday Night Fever." Only five times in the past 20 years has an artist or group won both record and album of the year.

In a broadcast that included a mass marriage of 33 couples, an aerial rope dance by Pink, and more Beyoncé for your buck, veteran acts were also honored. Led Zeppelin scored its first-ever Grammy as the group's live album "Celebration Day" won the rock album award. And Black Sabbath won the group's second Grammy for metal performance, while Kris Kristofferson took home a lifetime achievement award.

With the music industry so fragmented and artists battling for downloads and royalties, does a Grammy award boost the bottom line?

Last year's winners would likely respond with a rousing "yes."

Winners and performers at last year's Grammy awards were rewarded with solid spikes in sales. According to Soundscan, Adele's album "21" saw a more than 200% boost in sales in the week following the 2012 Grammy Awards, held February 12, 2013. Even her debut album sold 144% more units.

Much of the awards show last year was a tribute to Whitney Houston, who died under 24 hours prior to the broadcast. "Whitney: the Greatest Hits" saw a 174% gain in sales, notching its best week since its release in 2000.

2012 Grammy Awards performer Bruno Mars saw sales soar 133%, the Foo Fighters' "Wasting Light" rose 134%, Mumford & Sons "I Will Wait" gained a 116% increase in download sales and Taylor Swift's "Speak Now" saw a 60% bump in sales.
