I do think that there is an unfortunately high percentage of pop that has fit so well in the "junk" category, that the negative connotations are somewhat justified. Unfortunately, there's a lot of good stuff too, that falls within the accurate definition of Pop (as in, massively popular), that does NOT fall within the negative connotations that often accompany the term.
It doesn't help, in my case, that "Pop" reminds me of bubble gum popping, which brings "Teeny boppers" to mind, and what we always called, "Bubble Gum Music." I hate the word pop, simply because of so many negative connotations associated with it. Like it or not, the word does have a bad rap, and that's why I don't care for it. If one of my own songs ever hit that chart though, I wouldn't care one way or the other. Not that it will ever happen. Maybe the fact that I can say that at all, is because I'm pretty damned sure it will never happen anyway.
