They are trying to create an illusion of their own sophistication. More cords, more sophisticated the song is.I've often wondered why music critics down the years have gotten so bent out of shape about the number of chords in a song. A song you love is a song you love, regardless of how many chords, notes or crotchets it exhibits, whether it modulates or undulates or has a flute solo or lute solo.
Or no solo. Or even a beginning......
But hey, those that can do ..... do.
Those that can’t .... teach or become critics.
