With all the stuff going on with Michael Jackson and the Beatie Boys publicly taking political sides. Some people may have a sensitivity to those demenors when listening to those artists' music and may choose not to listen to them anymore because their private lives come out in the open. They may be less desirable to associate that with the listening of the music.
Me personally, for the most part it does not affect me really. I love the Beastie Boys more than ever. I still enjoy listening to a number of artists regardless of what they believe in or do. I enjoy the music for the music.
