I'm the f*cking end-all, be-all of music.

The line is an extreme statement of artistic supremacy: the speaker claims to be the ultimate standard (“end-all, be-all”) by which music should be judged. Read rhetorically, it functions as braggadocio in the hip-hop tradition—an intentionally inflated persona meant to project confidence, dominance, and cultural centrality. It also reflects a recurring Kanye West theme: collapsing boundaries between personal identity and artistic output, where self-belief is framed as a prerequisite for innovation and influence. The profanity intensifies the performative aggression, signaling defiance toward critics and competitors and asserting authority over taste-making institutions.
