Why rap doesn't ALWAYS suck

This song (go look at all the lyrics):

Big Mama, my grandmother, my main girl
I love you much more than the scandalous world
As a young boy you gave me whoopings to save my life
Cursed me out, to keep me out the streets at night
...
I love you baby, you the one and only, that's a fact
'Til death do us part, I'ma always have your back
You beefed cause you heard that I was cursin in my raps
Eighty-six, still you wanna run and get the straps
...
I dedicate this to the Big Mama's everywhere
The ones who raised us - when nobody else was there
...

Please God that we all remember where we came from as clearly as LL. The man is just cool as can be.
