point taken re classical terms, they're always insuffucient, but if we are considering all of these types of music i.e hip hop, metal, folk, electronica, dance, rock, r+b, jazz, blues, soul, world......- then by asking us to say what's good about pop you're in fact asking what's good about hip hop, metal, folk, electronica, dance, rock, r+b, jazz, blues, soul, world etc ,and the statement that they are all based on similar chords is now obsolete since its obviously not the case. In my opinion music other than "classical" is equally as popular, it just isn't as accessible on television, radio etc hence we don't hear as much about it. Who knows what direction popular culture will take, but people will continue to like it because its spoonfed to them!
