Im not trying to get in the middle of a E fight or anything but name a rapper that DOSENT quote someone else or use other peoples lines in there shit. Some of the coldest rhymes Ive heard reference other peoples lines but they use that shit in a new way and keep it fresh.
And please dont say you dont reference other rappers shit. If you use a beat sample, talk about women, fighting, or cops you might have "bit" someone elses shit
