Mistletoe

"Mistletoe" is the first single by Canadian recording artist Justin Bieber from his second studio album, Under the Mistletoe. The track was written and produced by the duo Nasri and Adam Messinger (aka The Messengers). It was released on 17 October, 2011. It sold 164,000 the first week putting it at number 5 on digital.

Bieber said, "I'm really excited. [The song is] really catchy. I know all my fans are going to love it. It's something that I feel like they're going to be singing every Christmas." Bieber first premiered the song live on the My World Tour on October 6, 2011 at Olympic Stadium in Rio de Janeiro, Brazil. During the performance, Bieber confirmed that the song would be released on iTunes worldwide on October 17, 2011.

"Mistletoe" is a Christmas song that is sonically derived from the pop and R&B genres, while making use of reggae elements. According to the sheet music published at Musicnotes.com by Sony/ATV Music Publishing, "Mistletoe" is set in common time with a "bounce" tempo of 80 beats per minute. It is composed in the key of A minor with Bieber's vocal range spanning from the low-note of E₃ to the high-note of E₆. According to many reviewers, the song's production and Bieber's delivery bears much similarity to Jason Mraz's "I'm Yours." Bill Lamb of About.com went as far as to call the song "'I'm Yours' goes Christmas." A Rolling Stone writer commented that "The song basically sounds like a laid-back Jack Johnson number with a bit of overdubbed sleigh bells."

The song presents the maturation of Bieber's voice, with RJ Cubarrubia of Billboard writing that he sounded "smooth and intimate." Lamb said "This track marks a distinct move toward a more adult sound on the part of 17 year old Justin Bieber." The song, which includes subtle "Christmas flourishes" in the background arrangement, opens up with jingle bells before an instrumental of guitar and bongos come in
