Just what I have been saying - the social function of pop music is to define and divide generations - Nirvana was meant for people my age into a certain area of punk rock not to like, it is just one of many generation breaks. Punk was meant for those into hip-hop and Motley Crue not to like (later pot unified a lot of the cliques, but that is another discussion).
The lyrics to most standards are dumb, sure, they don't have the baggage pop carries its own time.
I don't really care about any standard outside of the historical aspect. Certain pop I am just sick of hearing about (Prince, Talking Heads, Eno) but understand an inherent quality. Other examples I just always hated for what it stands for as well as what it sounds like (Nivana, Motley Crue, Grateful Dead, Steely Dan etc.) even certain pop musicians like Sting and Elvis Costello who maintain high musical standards are just adult contemporary fluff to my ears.
Lots of people wouldn't like the pop music that doesn't irritate me. Pop music is something people rarely feel neutral about.
We are just not going to find a meeting point with any of it - certainly not as wide of a common ground as the old standards and music written by jazz masters.
