So this is a little late, but I wanted to expand on our discussion about misogyny, sexism, and homophobia in other forms of music besides hip hop. I'll just give a few examples of what I've found.
Rolling Stones - "Under My Thumb"
Its down to me, oh yeah
The way she talks when shes spoken to
Down to me, the change has come,
Shes under my thumb
Yeah, it feels alright
Under my thumb
Her eyes are just kept to herself
Under my thumb, well I
I can still look at someone else
There's a song by Kenny Rogers called "Coward of the County" about a man who avenges his lover's gang rape by killing a bunch of people. There's also one called "catholic girls" that is interesting.
I guess my point is to agree with our discussion in class that these sorts of offensive lyrics are not just in hip hop/rap. If you search for misogyny in music though, you're likely to find a bunch of information on hip hop and misogyny.
