Why does American pop music sound so superior to other pop music in English language?

I've been listening to other pop music from around the world, UK, Australia, my own country when singing in English and so on. But somehow, at least to me, American pop music sounds better, catchier. The other pop music sounds too generic. Is it just me or is it the real thing? Is it because Americans invest much more money and talent to production and songwriting? Or is it maybe because everyone is too exposed to American music on the radio and online so it starts feeling superior.
