The 'nefarious meaning' topic is very interesting, especially in relation to the lyrical content of a song. For example, a guy I know plays a lot of old blues songs, many of which are about 'going out and shooting my woman dead cos she done me wrong' sort of thing. Does this mean that people who like to play and listen to this style of blues music condone misogyny? (the same would apply to modern day rap music which also has some nasty attitudes towards women). Personally, I think it is possible to like the music in spite of the imperfections of the artist (I mean, nobody's perfect) but if it was a subject I felt strongly about, I couldn't help feeling biased against it, anyway.
