The song was the first to be released from Bieber’s 2012 album Believe. It gained a lot of attention due to the sound — much different from Justin’s other material.

With “Boyfriend”, he proved that he wasn’t the innocent kid with a high pitched voice anymore: it marked the beginning of a new era for the singer. He got a new haircut as well and released the music video for the song, which shows him driving expensive cars and dancing with pretty girls in a way he hadn’t done before.

The new sound didn’t make him lose fans; Justin’s “Beliebers” had grown up as well and were ready for this more mature, yet still catchy and appealing music.
