Baby by Justin Bieber

This is the most popular song by him. I like One Less Lonley Girl and One time more, but I decided to add this because it is his newest song and it's really popular, like I said.
It is pretty and Bieber keeps repeating the word baby in it. It also features Ludacris. There is no official music video so don't complain...
