Personal Narratives and Representation in Hip Hop

Here are two tracks from MN rappers that are in the genre of personal narrative.  Both deal with the issue of representation in interesting ways.

In POS's track "De la Souls", he calls himself "the new generation of slaves".  What would it mean to be the new generation of slaves?  To what extent are certain communities denied rights or privileges in a way analogous to slavery in the early history of our country?

In "Win Some Lose Some", Brother Ali discusses his own experiences growing up as a a picked-on and looked-down upon young man.  In "Picket Fence", he describes his life growing up.

Both tracks deal with the issue of representation in interesting ways.  How does POS represent himself?  As part of what group?  What about Brother Ali?  Given his stage name and the content of his music, how would you label the group to which Brother Ali belongs?  What constitutes membership in this group?
