Ice Ice Baby

I asked the guest lecturer if she thought that eminem's contribution to hip hop was a form of black faced minstrelsy and she said , no. After some considerable thought I am obliged to agree with her. However, if I had it to do over again I think my question would focus on Vanilla Ice and whether his contribution to hip hop was a form of black faced minstrelsy. I believe it was since there is some evidence that the lyrics for the song "Ice Ice Baby" were actually written by a black performer and that Vanilla Ice made his claim to fame with that song.
