I'm not making an argument on music style, or judging it out of the blue. No; I would not know anything was wrong if I had never heard of the BEatles before. I didn't know anything was wrong when I had heard of them, but didn't know about their drugs, false religion, and veiled references in the songs. But once I became aware of those things; then it called into question their whole spirit benind their music, and their trustworthiness as artists I should listen to.don't see how you can say there are discernable hidden messages. It's just silliness. You have to bring in all this knowledge about lifestyles, the era, drug usage, etc. etc. which exist completely external to the music. In other words, these supposed bad messages you believe are there are not based on the music itself but on some belief that men magically attatched them to the music. There simply is no logical defense for such thinking.
If I had never heard of the Beatles before, but heard the song Octopus's Garden and loved it, how would I be able to know it was sinful based on your teaching of hidden messages?
You have to judge all works on their own merits. Nothing else makes sense.
Then you start thinking "Just what are all of those things they are singing about?" What is the Sun King? Mean Mr. Mustard? (I know that those, or at least the latter is from Yellow Submarine, but then being exposed to that several times in the grammar school auditorium, what on earth are all of those things in that movie?)
If the Lucy in the Sky interpretation happenes to be urban legend like Puff the Magic Dragon; then maybe it is wrong; but is that really aun urban legend? They were into drugs and false religion (which opens one up to demonic psychedelic type visions and stuff, anyway), so it is not surprising. Their lifestyle and philosophy seems to confirm these legends, and casts doubt on their appropriateness for the Christian home.
They create their own "bad association"; so then we can say "evil communication [the lifestyle, religion/philosophy, gimmicks, references to these things, etc; not the music style] corrupts good manners", and "avoid every appearance of evil".
