New-School rap is the gay, bling-bling, "killing faggots, pigs, bitches, and hoes," fucked-up-ass bullshit we hear on the radio today! If you want to hear real rap, listen to the old-school. You can't go wrong.
New School rap, by today's standards, is 50 Cent, Eminem, and all these retards who are currently on the goddamn radio.
Old-School rap, by today's standards, contains all the great artists who have risen to fame before 1995. These artists contain, House of Pain, Cypress Hill, Run-DMC, The Beastie Boys, NWA, Naughty by Nature, The Sugarhill Gang, Eric B. & Rakim, etc.
