Justin Bieber - Beauty And A Beat ft. Nicki Minaj (Video clip)

"Beauty and a Beat" is an uptempo EDM and electropop melody that keeps going 3 minutes and 48

seconds. With the harmony movement of F-Dm7-Am7-Gsus, the tune is composed in the key of A minor.

The melody contains components of R&B. Sarah Deen of Metro portrayed it as a "berserk move track", while Rolling Stone's Jon Dolan called the tune a "disco-inferno". "Beauty and a Beat" contains quick paced rhythms and a corrosive house break down. Bieber's then-sweetheart Selena Gomez is referenced in the tune amid Minaj's rap: "Justin Bieber/You know I'm going to hit them with the ether/Buns out, wiener/But I gotta look out for Selener." Jason Lipshutz noticed the rhyme amongst "wiener" and her given name
