It's Cole, it's only right I brought back the soul
Y'all got way too electro, damn near techno
Halfway homo, way too metro

from J. Cole – Grew Up Fast Lyrics on Rap Genius

Meaning

Cole is suggesting that rappers have forgotten original hip-hop/rap beats and have moved on. He’s bringing hip hop back to old school, smooth soul beats instead of this techno shit these days. Reminiscent of this Kanye line. .
