Dude, open your eyes! John Lennon is an artist of our time because the themes that informed his music are, sadly, as relevant today as they were when he was alive. In a world ravaged by war and corruption, as ours most assuredly is, how can anyone with half a brain think that John Lennon's message isn't relevant to our time?
Lennon spewed a lot of socialist, pseudo-utopian garbage. Very typical baby boomer, he had his head firmly planed in his ass and you see that come out when he gets political in his music. Not all of it is like that but when he does, it's just nauseating.
