Musically, “Boyfriend” is a R&B influenced song that features pop beats reminiscent of American record producer Pharrell Williams and boy band ‘N Sync. The instrumentation is kept in a lower sound to highlight Bieber’s vocals. However, critics dismissed the lyrics as immature and silly. “Boyfriend” was a commercial success, debuting at number two on the Billboard Hot 100 after selling a total of 521,000 digital units of the single. The song is the second-highest-ever debut digital sales week in the United States (after Taylor Swift’s “We Are Never Ever Getting Back Together” which sold 623,000 in its first week), and has also charted at number 9 on the Pop Songs component chart. It also debuted at number one in Canada and number two in the United Kingdom.
