"I feel like they keep beating me...
I feel this all so vividly
I'm losing my identity...
I'm Trayvon Martin"

"Dollar Day" by Mos Def is about Katrina:
"Mr. President is a natural ass
He out treating niggas like they treat the trash"

"King died for us niggas living in poverty
Fifty years later we still don't have equality, it bothers me"
