No criticism intended, just a friendly warning, strictly FYI.

"Caucasian" can be used to describe a genetic type of person. If used for a type of music or culture, it refers to the region of the Caucasus mountains. Any other usage is dangerous.

"In the Ghetto", "Lion" etc.: there must be Mudcat threads about them. Perhaps someone invites our friend Azizi to comment, our specialist for African-American identity. Anyway: if your friends like to sing those songs, who am I to object; I just do not want to propose them.
