I think Touch is the best song, although I wish there was more singing on it; the melody is so great. Overall it's a mixed album to me. The first two tracks are somewhat forgettable - the first track feels almost generic, like Studio 54 elevator music, and the vocals are forgettable. The Game of Love and Within both don't work to me either; Daft Punk has done downtempo stuff well before (Something About Us) both these just don't have a compelling sound to me, and just drone on.
Giorgio by Moroder is good, and I like Instant Crush. Lose Yourself To Dance SHOULD be the best song on the album, and one of the best of the year; the melody, the guitar, that amazing bass...but I just don't like Pharrell's singing. He sounds like some guy with a nice but limited voice doing karaoke. Same problem I have with Get Lucky. Not saying they're bad songs, they're just frustrating because you can tell a better singer (preferably female) would turn them into truly great songs.
I don't get the love for Contact. It has such a big build up but when you think you get to the climax there's...nothing. It's like the middle of a 70s prog rock song, except it ends instead of exploding into some jam.
