Well I'd say at the NWA ones, maybe OG Original Gangster by Ice T, The Chronic by Ice Cube and at least two Wu Tang Clan ones. Its funny thinking of posh kids driving their Mum's 4x4 into town from a sleepy home counties village listening to a song about dying young from a gunshot wound in a liqour store in front of your some woman you've just raped with an Uzi and a bottle of Hennessey. Heh heh.
Just an observation that's all. Any other ones?
