Kanye's use of Daft Punk's "Harder, Better, Faster, Stronger" on 2007's "stronger" wasn't just unconventional; it opened up a much wider audience to the Daft Punk's work, incorporated one of their best songs without losing the overarching aesthetic of the original, and became Kanye's third No. 1 single, after "Slow Jamz" and "Gold Digger," announcing a completely new direction for the rapper that would only increase his audience. It was also a major indicator of how the dynamics of Kanye's music had changed.
Kanye West wasn't the only hip-hop artist to sample Daft Punk; Swizz Beats had swiped "Technologic" for Busta Rhymes' hit "Touch It" in 2005. But Swizz's flip just swiped the original vocal line, just another texture in Swizz's late career resurgence. For Kanye, it was the whole bag.
After Kanye reportedly introduced to the duo's music through his DJ, A-Trak it became obvious that he understood the wider possibilities of the group's approach. It was stadium music, a way for Kanye to reach a larger audience than ever, with the sonic capabilities to fill many of the larger arenas he was now reaching. It's no coincidence that, for his Glow in the Dark tour, 'Ye also began to take on influences (as did every EDM artist since) from Daft Punk's performance at Coachella in 2006. Not unheard of in music, maybe; in hip-hop? Unprecedented.
