Most rappers nowadays suck in my opinion because they make no sense and do what they do only for the money and the chicks. Some rappers nowadays, like Benefit for example, are not old skool but rap in the same way, therefore it is old skool style but not old skool.
These artists and their songs:
The House of Pain-Jump Around
Cypress Hill-Rock Superstar
and many more....
yo wat up dawg, them lasses is chekin us out and they would look mighty fine in da bak of my old skool caddie!
