Curtis "50 Cent" Jackson has revealed that he didn't have to work very hard to come up with the chorus to his most popular song.

"Go shorty. It's your birthday." When these lyrics began to circulate around schools, clubs and radio waves 15 years ago, it's unlikely that even 50 Cent himself realised In Da Club would become the rapper's most popular song. But apparently these lingering words weren't very hard to string together.

In a recent interview, Jackson revealed that it was the simplicity of the phrase that made it so appealing to the masses. "It's not rocket science," Jackson said. "Every day is someone's birthday."

"Simplicity is the key to a lot of success in entertainment," he said. "I didn't have to study in order to write those lyrics. It just came out when the music was playing."

In fact, the rap star has previously revealed that he can spend hours working on his songs "and not even feel it". He added: "There are no windows so it's very easy to lose track of time." However, he's admitted that even his biggest successes usually need some editing. "There are always notes on a project," he said, because everyone "needs a reason why they're getting a check."

Jackson created "In Da Club" in 2003, co-writing it with Dr. Dre and Mike Elizondo. Following its initial release, the song rocketed up the charts, earning Jackson a nomination for Best Male Rap Solo Performance and Best Rap Song at the 46th annual Grammy Awards.

It has since been reproduced by a number of internationally renowned artists including Beyonce, Mary J. Blige, P. Diddy and Lil Wayne.
