Executive Meddling: It's widely believed that Hans Zimmer was brought in by Disney to "touch up" their soundtrack to TRON: Legacy, despite being uncredited in both film and soundtrack album.
One-Hit Wonder: In the eyes of mainstream audiences, "Get Lucky" qualifies. It would have reached #1 on the charts in the U.S., but had to settle for 2nd as Robin Thicke's "Blurred Lines" was released about 2 weeks later and dominated the summer. Their follow up "Lose Yourself to Dance" barely got any airtime at all on any radio stations that didn't focus on EDM, and is barely a blip on iTunes. Though before this one could have argued that "One More Time" was the group's only big hit among the mainstream. Thankfully, the sales of all albums, extra attention from big name fans (like Kanye West), appearances and such in games and movies like DJ Hero and TRON Legacy, along with the dedicated fanbase, have kept Daft Punk from falling into obscurity like other groups that were only one-hit wonders to mainstream radio audiences.
Reclusive Artist: Appearance-wise, at least. Although photos of their faces very early on in their career do indeed exist, most of the time, they always cover up their faces with something, usually their iconic robot helmets. The band have also gone on record saying that they use the robot image to keep their Daft Punk and personal lives separated.
