Q: there has to be something about this that is objectively more pleasing than other chord combinations to the human ear, else the same formula wouldn't work again and again as it does now to make hits. The number of combinations that achieve the same effect must be limited and there has to be a pattern to it. Isn't that what studying music is all about?
A: yes but don't forget to put lyrics and melodies in too, or at least something besides just the chords, otherwise you might not have too much going for you
