I'm watching the film Yesterday. It's very good. The premise is that a solar flare or something causes The Beatles to have never existed, everybody forgets them. However, there is one person can remember their songs. He wows people with songs like 'Yesterday' and 'The long and winding road', people keep saying they're the best songs they've ever heard etc etc.
My question is, are they really the best songs ever, objectively? Some are incredibly simple and some super weird. Or are they significant because of what they represented at the time in the 60s, or how people born since then have experienced them through their parents?
