The rapper explained that his new album Life is Good was inspired by his "early '90s roots" and the lack of traditional rap music in the charts today.
He told Digital Spy at BBC Radio 1's Hackney Weekend: "My new album is just about feeling life and not letting anything get in the way of living life.
"The only thing that got in the way of the album is how music sounds today. It's the perfect time for me to do the music that is true to my early '90s roots and make it appealing today. I just let it flow."
He continued: "The sound came back naturally to me in my case because I was part of the '90s rap renaissance. I went back to that era back in my head and went back to producers from that time as well as ones who are only just starting out.
"It's up to this generation and the next to decide what they want to listen to. I have a different take on today's charts compared to the younger crowd and I don't let appealing to them bother me anymore. I spoke a bit about it on my Hip-Hop is Dead album, but I'm past that now and I'm inspired again."
The 38-year-old insisted that he was "past that stage of getting nervous" over album releases, adding: "It's more about how I progress now as an artist from my last album to now. I'm just happy that I still like to make music. It's what makes me happy."
