New edition cool it now
You're referring to the popular 90s R&B group Coolio's hit song "Gangsta's Paradise"!
The song was released in 1995 and became a massive hit, reaching number one on the Billboard Hot 100 chart. It was also featured on the soundtrack of the movie "Dangerous Minds".
The song's lyrics, which were written by Coolio and WC, addressed issues of poverty, violence, and social inequality in urban communities. The song's chorus, sung by L.V., features the iconic hook "This world is a gangsta's paradise".
The song has since become a classic of 90s hip-hop and R&B, and its influence can still be heard in music today.
