... as a follow up to my last post, I'd like to mention that BOOOOOYAH you can find a HIP HOP section in Norton Anthology's African American Literature canon.
Check out the Table of Contents if you don't believe me:
The Norton Anthology of African American Literature: Book Contents
Scroll down. Works include some Grandmaster Flash & the Furious Five, Queen Latifah, Public Enemy, Biggie, Nas, and Rakim. Not to mention Marvin Gaye and Stevie Wonder appear in the Rhythm & Blues section. WHUT WHUT hip hop, legitimized. Now, if we could only introduce it into the larger, American Lit canon... but that might still be a while.
