ELI5: Why does music “make sense”, why can we predict/expect the next musical notes having never heard the melody/song before?

I get the idea of certain melodies being used in different songs, but it happens sometimes even with unfamiliar melodies/songs. Is this a known phenomena? how do you explain this?

Western music follows lots of established patterns, and melodies and chord progressions often “resolve” in similar ways—for example, by ending on the same note they started on. Since we’re inundated by music all the time, our brains learn to recognize and predict patterns the same way they do for everything else. 

A songwriter or composer can create tension by subverting expectations.
