London, Oct 2 (IANS) Singer Jay-Z says hip-hop has become more ‘mellow’ over time and he thinks that is due to the drug consumption of some of his peers.

‘Public Enemy were a great force in the 80s. Chuck D was a powerful speaker and a great thinker. The intensity of life on the street in the 80s is right there in that mix,’ contactmusic.com quoted the 41-year-old as saying.

‘Hip hop sounds get mellower in the 90s, when people started smoking more weed,’ he added.
