There are some really innovative techniques in electronic dance music. Right now, I'm comparing sidechain compression with reverb to the guitar on "Get Lucky"... but because I'm a guitar player, I'm very biased.
But saying Daft Punk is just "One More Time" is like saying The Doors are just "Light My Fire".
Maybe I'm just a little too familiar with their catalog, but they've been a mainstay in my life since Discovery. And I'd heard "Around the World" (Homework) before that... It's a sound that I'll never forget.
I think they remind me of funky disco house a little, just because... oh, I don't know. They just do. The sounds that they incorporated took me to disco-nostalgia - I don't have a history in disco, but it has a place in history and is ingrained in dance music history as well.
At the time I started listening to Daft Punk, I was very much into DJ Dan (see funky house), and DJ Irene (very much a hard house pioneer). Those were the sounds of that time, and Daft Punk placed themselves squarely between all of that with zeal, creativity, and more-than-a-little enthusiasm.
I like that they were in Tron Legacy. It's a testament to the popularity of dance music - proof that we exist outside of the walls of the club, beyond the grass at the festival, and as more than a mere music-collector/hobbyist's fantasy. We're real, and Daft Punk is proof.
Farewell... you will never be forgotten.
