6. Painfully bad white-boy rapping — and you’ll see more before you’re done with this list — is a delicate business. It requires a certain ironic detachment; painfully bad rappers have to be in on the goof. Ideally they deliver some good information, because if you gotta suck, you might as well suck informatively.

On all these scores, Darrick “D-Pain” Lee and Michael “Phat Mike” Darnel get a solid C. That’s C as in Canada, Land Where Laughing-At and Laughing-With Meet. These Vancouver hip-hoplings’ debut joint, “Hurtin’ Our Planet,” loses points for hectoring but gains ‘em right back for the use of autotune.
