As a remix album, this is automatically flawed. They all are. But if you loved Discovery and couldn't get the Daft Club thing to work online, then this is well worth a look in. Some big remix names (the Jaxx, Demon, Phoenix, Boris Dlugosch, etc) realise they can't better the original tracks, so wisely offer their own subtle spin on Daft Punk's sound.
Highlights include the Neptunes remix of 'Harder Better Faster Stronger', which is a pretty mouthwatering combination, and Daft Punk's own cut up of 'One More Time' over 'Aerodynamic'. Trust me, you'll never again be able to hear the latter without singing the former over the top! But the surprise package is Gonazales' inspired Lounge cover of 'Too Long', sung in the club style.
And, ok, the tracks were previously available online, but credit to Daft Punk: they didn't have to release them online at all. The Daft Club was an original, generous and very clever way to get fresh material to fans for nothing when many other acts and labels were decrying the internet as the root of all evil. I certainly don't begrudge them releasing the material to those who couldn't download it or who, like me, wanted a nice vinyl or CD copy to play out and about.
