Music Conundrum

Why is it that music is objectively the most powerful artform, yet most people who work within it have, of all artists, the least interesting things to say?

I love you.

I miss you.

I lost you and I wish I still had you.

I hate you.

Now listen to this song that says one of these four things over and over intermittently for the rest of your life.

Bravo, songwriters, bravo.
