“Baby” is about breaking up with someone you love and still wanting them even after you’ve broken up. It’s the lead single off of Bieber’s debut album, My World 2.0. It debuted and peaked at number five on the Billboard Hot 100 in early 2010.

It’s also one of Justin Bieber’s most popular songs of all time, with it being certified 12 times platinum by the RIAA; it was also an international smash hit that included a #3 peak in the UK.

“Baby” was the most watched video ever in July 2010 on YouTube until “Gangnam Style” surpassed it two years later.
