Which rapper's hit 'In da Club' was released in 2003?

50 Cent released the hit 'In da Club' in 2003. The song became the lead single from his debut studio album, 'Get Rich or Die Tryin'', and was released digitally in the United States on January 7, 2003.

Written by 50 Cent with producers Dr. Dre and Mike Elizondo, the track introduced Curtis Jackson's distinctive voice and street-focused storytelling to a huge mainstream audience. Its memorable opening and club-ready production helped make it a defining rap hit of the early 2000s.

'In da Club' became 50 Cent's first number-one single on the US Billboard Hot 100, where it stayed at the top for nine consecutive weeks. It also earned Grammy nominations for Best Male Rap Solo Performance and Best Rap Song. A common mix-up is crediting Dr. Dre because he produced the record, but the performing rapper and credited lead artist is 50 Cent.
