'I Get Money'
Featured on 2007's 'Curtis,' this 50 Cent song samples Audio Two's 1987 'Top Billin.'' The single was later released as a remix -- entitled 'Forbes 1-2-3 for Billion Dollar,' it featured rap moguls Jay-Z and Diddy.

09
'P.I.M.P.'
Known for it's steel drum melody, the song was later remixed to feature G-Unit's Snoop Dogg, Lloyd Banks, and Young Buck. The Chris Robinson-directed music video stayed on MTV's TRL for 50 straight days, and earned a MTV Video Music Awards nomination for Best Rap Video.
08
'Disco Inferno'
Featured on 2005's 'The Massacre,' it's infamously paired music video drew controversy -- mainly due to the soft pornography. The video features porn star Daisy Marie as well as Nick Cannon.
07
'Candy Shop'
A runner-up to his party-tune 'In Da Club,' this song features R&B artist Olivia and Middle Eastern influences (the latter credited to producer Scott Storch). Critics claimed the song was too similiar to 50 Cent's previous collaboration with Lil' Kim on 'Magic Stick.'
06
'Baby by Me'
The offical single on 2009's 'Before I Self Destruct,' this 50 Cent song features Ne-Yo. As a promotional stunt, 50 Cent launched an iPhone app with the song, which tells you how much you'd make if you had a baby by him. You can even receive advice from the rapper himself, and share with the world how much 50 says your worth through Twitter integration. Like he says in the song, "Have a baby by me, baby, be a millionaire."
05
'Best Friend'
This 50 Cent song is featured as a bonus track on the 'Get Rich or Die Tryin'' soundtrack and samples the beat from Valerie Simpson's 1972 'Silly Wasn't I?' as well as references the chorus in Biz Markie's 1989 'Just a Friend.'
04
'Just a Lil Bit'
Released as a single in '05, the b-side features a live performance of 'Disco Inferno' on AOL Sessions (you can check out the video here). T-Pain released a spin off called 'A Little Hit' sampling the instrumental part of 50's song.
03
'Hate It or Love It'
50 Cent is featured in this song, which was released on The Game's '2005 'The Documentary' and samples The Trammps 'Rubber Band.' The music video is filmed in Compton, California, and Jamaica, Queens, to showcase 50 Cent and The Game's tough upbringing.
02
'21 Questions'
R&B singer Lil' Mo released an 'answer back' remix titled '21 Answers,' which is frequently mashed with 50 Cent's version at clubs. Producer Dr. Dre initially did not want the song on 50's debut album, for he thought the sappy "love song" might discredit him as a gangsta rapper.
01
'In Da Club'
Eminem discovered 50 Cent and introduced him to Dr. Dre; the result is 50 Cent's first No. 1 charted single. His night club jam earned him Grammy noms for Best Male Rap Solo Performance and Best Rap Song, as well as wins for Best Rap Video and Best New Artist at the 2003 MTV Video Music Awards.
