Nearly every human being enjoys music. Many of us enjoy listening to music with lyrics that we would never speak or write. Many of us would never, ever, say the 'n-word' even if it is being used casually in our favorite songs. Some very thoughtful feminists listen to, dance to, and exercise to music that degrades women. Whether you are listing to pop music, or venturing into artists such as Brotha Lynch Hung (I never heard of him, but one of my students told me about him as an extreme example when we were discussing this question in my philosophy class), a lot of contemporary music contains hateful messages and glorifies violence.
Put aside, for the sake of this question, any empirical claim that such music actually causes us to act immorally. Also, let's assume, for the sake of this question, that you are not a hater, and that you are morally opposed to racism, sexism, gratuitous violence, etc. Are mere listeners/consumers, morally guilty in virtue of providing a lucrative platform for hateful expression? Are we, as a mere listeners/consumers, morally guilty in virtue of nurturing a pop culture where degrading ideas are hummed along to and barely even noticed. Are we immoral accomplices or innocent bystanders enjoying music?
