"Stronger" is a song by American rapper Kanye West, released as the second single from his third studio album, Graduation (2007). The production was handled by West, with an extended outro co-produced with Mike Dean. The composition is electronic in nature, employing synthesizers as its prominent instrument. For the track, West utilizes a sample of "Harder, Better, Faster, Stronger" by French house duo Daft Punk consisting of a vocoder-affected vocal. On "Stronger", West speaks about the resolve that comes when one is faced with adversity, with lyrics at the song's refrain that paraphrase Friedrich Nietzsche's dictum "What does not kill me makes me stronger". West also describes "Stronger" as an "emancipation", using the track to vent his frustration over mistakes he made in the past year.
