Certainly both, but in your question, I'm suspecting your unaware of how much of this music you're familiar with it since it lives rent-free in the general zeitgeist. For example, I suspect you'd recognize Satie's work Gymnopedie no. 1[1] and perhaps putting a name to it will give you some appreciation for why his work is valued
Talk about living rent free…the number of modern songs which are (generally obliviously) derivative of Pachelbel's Canon in D is mind boggling, which itself was surely built upon even earlier, similar chord progressions.
