For me, Daft Punk's best album will always be Discovery, but there'll also be a place in my heart for the rest of their catalog.
One that I have heavily in rotation for the past year is Alive 2007, with the hard-hitting remixes and the epic concert. Great song choices.
The concert! I feel you on this one, this is also one that I play in the car a lot actually, a super sweet set!
Sadly, they didn't perform anymore after that. At least we'll have that epic set.
