Fourth single taken out of the album [Discovery](http://www.discogs.com/Daft-Punk-Discovery/master/26647). Contains samples of "Cola Bottle Baby" performed by [Edwin Birdsong](http://www.discogs.com/artist/Edwin+Birdsong). Vocal parts of 'Harder Better Faster Stronger' were later sampled by [Kanye West](http://www.discogs.com/artist/Kanye+West) in his single ['Stronger'](http://www.discogs.com/kanYeWest-Stronger/master/8446). Daft Punk accepted the sampling issue and even performed 'Stronger' live together with West on the 2008 edition of the Grammy Awards.
