what artist degrade females and in what kind of way?
Well, I am not certain what you mean by artist. Eminem is unquestionably insulting, degrading, and pandering to violence and explotation when you listen to his "music". I consider it garbage, not art, but the beauty of art is in the eye of the beholder.
Some men like mud westling, or jello westling (and names like Naughty Nancy the Nurse), I consider that degrading to women. Is it an art form?
I remember some poems, one of them is mentioned here, it is a monologue describing a painting of a woman murdered in a bad relationship. This article is probably food for thought.

However, to answer your question, Eminem and several other Pop and Rap artists come to mind. They have very bad things to say about women.
