I'm not sure. I've never been able to figure that one out. For one thing, Van Morrison himself has publicly stated that he does not like Pop Music; he grew up listening to jazz, blues, country, R&B, and maybe some early rock n' roll. He developed a highly unique style throughout his career that may not always reach the mainstream, but all of his albums are interesting and worth hearing. As for The Beatles, all they were famous for was their image and dreadfully overproduced pop music. I've never understood people's fascination with them, and I never will. Even Van stated that he doesn't even admire the Beatles, or Elvis for that matter. So the unfortunate answer to the question is that people choose manufactured crap or over genuine musical talent.
