'Beauty and a Beat' debuted on the US Billboard Hot 100 at number 72. It re-entered the chart after the release of the song's music video and peaked at number 5 position. Justin Bieber wrote this song's music video's storyline himself and co-directed the video.

Songs give us a peek at the future of music. Sure, the Biebs is only 19, but in his short career the Canadian crooner has already surpassed double-platinum status and continues to crush Billboard, YouTube and social media records. Not only that, but Bieber virtually reinvented teen pop, proving that his hits can move people of all ages to the dance floor and he can make anyone a Belieber, earning him the respect of his fellow musicians. Now, many of music's most iconic artists jump at the chance to work with the kid who melted hearts with his boyish good looks, unreal dance moves, and a little tune called 'Baby.'

• 10 'Pray' (Acoustic) In 2010, Bieber reminded us what makes him so darn easy to love. Not only is he cute and makes ridiculously catchy music, but he's charitable too. Biebs dropped 'Pray' as a single in Europe, but it's just as popular in the States and Canada. The song, which appears on the 'Baby' singer's 'My Worlds Acoustic' record, breaks down all of the things that are racing through the world-famous teen's head and keeping him up at night -- world hunger, sickness, homelessness. With this track, he inspires us to make a change together and to never give up hope.

• 9 'As Long as You Love Me' Feat. Big Sean This -assisted dance track is one the Biebs' stickiest tunes from 'Believe.' This feel-good romp makes you want to leave your drink at the bar and hit the floor to dance your face off.

The sizzling song is Bieberized dubstep; that is, it's the teen's take on a hot genre at the time. He had his way with it and came up with an unforgettable song that's got a lot of parts, but meshes seamlessly and doesn't feel mired in a trend. The studio effected vocals are punctuated by Bieber’s newly-honed falsetto, demonstrating a range we didn't even know he had. • 7 'One Less Lonely Girl' 'If you let me inside of your world, there will be one less lonely girl,' the then 15-year-old Bieber promises on this track, which was written by his mentor,. Unfortunately, that's a big fat lie -- girls all over the world have allowed Biebs into their world, be it in poster form, perfume form, or simply with his music, and millions of them are still pining after 'Baby' hit maker. Still, this song delivers poetic lines for other guys to use in order snatch up the lonely girls. Which, we suppose, makes Justin Bieber like a modern-day cupid.

Hey, maybe that should be his next business venture? Babes by Biebs, perhaps? • 6 'Yellow Raincoat' Written after his much-publicized split with, this spare track from his acoustic release presented the Biebs at his most vulnerable. It was nothing more than gentle strumming and his delicate, quivering voice, and found Bieber laying his emotional cards face up on the table.

While it might not have impressed Gomez, it paid off with fans and critics. The track was an incredibly brave move, a peek that we don't often get, but the dividends were there, since he put his cockiness in cold storage and let us feel his emotions with him. It was a first taste of the real Justin Bieber. Yes, this is a sleeper track, yes, so why not wake up? Our recommendation is your alarm clock.
