Your grandparents are full of crap.
As they grumble about how rap music is destroying civilization, what they don't mention is that the blues they were listening to in the 30s and 40s could be every bit as violent, sexually explicit and sometimes just downright insane as the worst gansta rap has to offer. Compared to some of these vintage lyrics the members of N.W.A are levelheaded concerned citizens, and Eminem's a regular damned feminist.
7Skip James Cuts a Woman in Half ("22-20 Blues" - 1931)
"22-20 Blues" tells the tale of a woman who just won't get her act straight. See, Skip James sent for her, on several occasions, and yet she didn't show up! The brazen audacity! Of course, in the world of blues, there's only one way to deal with minor punctuality issues: brutal, brutal murder.
Big on punctuality.

Sometimes she gets unruly;
An she act like she just don't wanna do;
But I get my 22-20;
I cut that woman half in two;

Shooting your woman with a mere .38 pistol? That's for pussies. Ironically James soon found himself humbled when Robert Johnson recorded a far more popular version of his song. The only real change Johnson made? He upped the caliber and named it the "32-20 Blues." It was all about the gun size with those boys.
6Lucille Bogan Fucks Corpses ("Shave 'Em Dry" - 1935)
Looking at a picture of Lucille Bogan, it's easy to imagine her as the motherly type, making breakfast and scolding you for your dirty mouth; but in reality beneath the modest exterior was the queen of the "dirty blues," and the writer of such classics as "Sloppy Drunk Blues," "Tricks Ain't Walkin' No More" and the "Bull Dyke Women's Blues."
Her most infamous song was "Shave 'Em Dry," a three-minute ode to her own humping prowess so filthy it would Lil' Kim blush.

I got nipples on my titties, big as the end of my thumb;
I got somethin' between my legs'll make a dead man come.

Say I fucked all night, and all the night before baby;
And I feel just like I wanna fuck some more.

And your dick stands up like a steeple;
Your goddamn asshole stands open like a church door;
And the crabs walks in like people.
Er, actually we take that back.
