I thought Jin was fukkin incredible! I was definitely a fan.
I remember watching this shyt live. Before they started I'm like: 'who's this random Chinese guy? the fukk is he doing here'.

Then dude started with "With a name like Hassan you should join The Taliban, because that's the only way you'll get Flex to drop a bomb" I was

In some ways, Jin didn't have enough talent to make actual songs (I remember that album being straight up garbage). And he's said that he didn't really soak up game when he had the chance. Dude had Just Blaze, Kanye (got one of Ye's top 5 all-time beats) and yet the songs came out half-ass. On another hand, there was definite racism involved.

A White dude can come into hip hop, not know a thing about the artform and completely vulture his way through... and some of us will be cool with that. But an Asian cat gets scrutinized more.
I haven't watched the Serious Jones/Jin battle in several years. I remember thinking that, aside from some very etherous lines from Serious, Jin actually won the battle. Serious came with the borderline-slurs and it was corny. It was obviously pre-written and this is before that whole pre-written, no-beat style took off. At the time, coming to a freestyle with pre-written rhymes was corny. Funny how things change.
