6. Somebody to Love

Somebody to Love is from Bieber's album My World 2.0 and was actually the B-side of the record Never Say Never. It was released as a single in 2010, though it was originally supposed to be performed by Usher on his record Raymond vs. Raymond, but it didn't make the cut. Usher did record vocals for a remix of the song.

Originally written by Heather Bright and The Stereotypes, a hip-hop production group, Bieber helped write the vocals for his version. The song was officially released on April 20, 2010, and managed to hit number fifteen on the BIllboard Hot 100 chart, though it did chart higher in other countries, notably number three in Japan.

The video for Somebody to Love is interesting in that it combines many different types of dance moves and exciting coreography, and includes several popular dance crews.

Eenie Meenie is a dance/pop hit with some of Jamaican-American Kingston's reggae thrown into the mix. When it was debuted on Ryan Seacrest's website, it became an instant hit. It was released for purchase a couple of weeks later, eventually peaking at number fifteen on theBillboard Hot 100 chart.

The video portrays the two singers being chased by the same girl, essentially what the song is about. It was a big summer song among teens and young adults in the summer of 2010.

4. Mistletoe

Mistletoe was from Bieber's 2011 holiday album, Under the Mistletoeand received mostly positive reviews from music critics.

Released in November of 2011,Under the Mistletoe immediately went to the top of the charts. It featured several popular artists, including Mariah Carey and The Band Perry. It is a compliation of Christmas standards and new more pop-flavored holiday tunes.

Mistletoe is the only single released from the album. It was produced by The Messengers, a Canadian duo that has worked with everyone from New Kids on the Block to Michael Bolton. Though pretty standard for Christmas fare, the song was well received by critics and fans alike, hitting number five on the Billboard Hot 100chart.

The video features Bieber in front of a snowy backdrop, as sleigh bells jingle.

3. Never Say Never featuring Jaden Smith

Never Say Never is actually the theme song for the remake of The Karate Kid, starring Jaden Smith and featured a rap verse by the famous Hollywood child of rapper turned actor Will Smith.

Never Say Never peaked at number eight on the Billboard Hot 100 chart and also appears on Bieber's Never Say Never: The Remixes album.

Baby is from Bieber's 2010 My World 2.0 album, which was the 'second half' of his debut record. It features rapper Ludacris and the song was first released for download on iTunes in January of 2010. The song only made it to number five on theBillboard Hot 100 chart, but it did hit number one in France and Scotland.

The video is a cinematic telling of the song, which is an attempt to regain lost love. It was said to be a 'remake' of the video for Michael Jackson's hit song The Way You Make Me Feel.

1. Boyfriend

Boyfriend is from Bieber's 2012 studio album Believe. It was previewed on the Ellen DeGeneres show in March of this year, and almost immediately went to number one upon it's release. It is Bieber's highest charting and best selling single so far. It is also the highest selling single of 2012 so far.

Believe is Bieber's most adult record so far, and is characterized by a deeper voice from the young pop star. It is the beginning of an effort to transition him from teen sensation to a more mature singer and hopefully reach out to more fans.

The first video for the song, directed by U Smile video director Colin Tilley, was actually scrapped in favor of the released version directed by Director X. Admittedly, the video has no concept, it just features things that young people are interested in, like cars and people hanging out. To date, the video has had over 60 million hits on YouTube.
