I can't go back in time because we don't have the technology to build a machine that could help us travel through time and I don't think we ever will. But if you actually did manage to somehow build a time machine, which I highly doubt, I would go to back to the 90's where hip-hop music was actually good. I'd be listening to rappers like Method Man, Big L, Mobb Deep, NWA, anything good coming from the east or west coast. I hate listening to fake millionaire rappers nowadays like Lil Wayne, Drake, and any other member of the YMCMB group doing it only for the money. 90 percent of rappers today are just terrible.
