On one of the many hits from his debut album, 50 Cent famously claimed, "If I can't do it, homie, it can't be done."

In the decade since, he's proven that such profound confidence wasn't without merit. He's sold millions of albums, launched successful business ventures into the worlds of film, fashion, energy drinks and audio products -- plus plenty more on that resume.

And now, he's tackling his next task: Getting you a job.

Kind of.

A recently-published research paper called "The Music of Power" in Social Psychological and Personality Science finds that listening to music can help affect the way that you feel about and approach a situation, and thus the way that you perform -- in everything from athletics to the workplace.

“One thing we know from prior research is that people who feel powerful tend to make the first offer in negotiations," explained Derek Rucker, one of the authors of the study and a professor at the Northwestern University Kellogg School of Management. "Essentially, power is a propensity to act, to take charge of the situation... Empowering music might be used strategically to get us in the right frame of mind.”

The researchers tested a number different songs and subjects to see how they would respond, and then broke them into "high-power" and "low-power" categories. 50 Cent and his anthemic "In da Club" were in that former category, along with songs like Queen’s “We Will Rock You,” and 2 Unlimited’s “Get Ready for This." Heavy bass was an important factor in determining the effectiveness of a song, according to the researchers.

So, next time you've got a job interview, or a big meeting with your boss, or a first date -- tee up that classic Fif.
