I love most pop music - but then, I love most music in general. Plus, 1) I don't care about whether or not I can relate to the lyrics, and 2) although I have a preference for experimental stuff, music doesn't have to do anything 'outside the box' for me to like it.
I do agree that pop music is not obviously experimental, but that seems to me to be almost a tautology. I mean, it's pop music. Of course it's not obviously experimental. This is the case for the majority of the mainstream music of most genres.
I disagree with your claim that pop music contains the same four chords over and over again. That's just false, and even if it was true, there is much more to music, for me least, than the chord progressions. From what I've heard, pop music is reasonably musically complex; the most musically simple genres are probably dance, rap, punk, and extreme drone stuff like early Earth (I like all of those genres, by the way).
