Haaang on, why did you go and choose a band with notoriously bad lyrics? Pure chance?
Anyway, what your saying is, you have no imagination? that, say you could derive no satisfaction whatsoever from, say, reading a Dickens novel, because you have not experienced life in the 19th century? You have no ability whatsoever to extrapolate emotional responses from aesthetics and imagery? You're saying that basically you are trapped in a sort of hellish now, with no real conception of the world outside what you've experienced? What you're saying is that music must somehow apply directly to the audience, so that you can only listen to Bob Dylans pre-electric albums if you were around in the sixties folk scene? After all, you know, I've never experienced the conditions as they were at that time, so none of that stuff really has any applicability to me, you know? I only listen to music about being middle class and white and going to a private school.
Could it perhaps not be that any fantastical imagery, into which emotions are projected, easily has the potential to give more to a far wider range of people than any song about an extremely specific incident ever could? Could it not be that the use of mythic archetypes is based around visceral stimulation of our folk-culture memory? Could it not be that some lyrics in fact disguise very serious messages under a thin veil of fantasism? Could it not be that some people have aspirations beyond a drab reflexive eternal now and, rightly dissatisfied with the state of the world, seek out music and artforms which lets them imagine other realities that might inspire them to set and reach their goals in this world? Could it not be that the use of imagined real world and historical settings also allows us to reflect on the human condition, even if the main purpose is only for visceral entertainment.
Also, you must reflect, if you quote lyrics and shit and talk about authenticity or how it speaks or anything, on the most entirely succint and meaningful lyric of any song. One second long.
