Well, Mario, I also agree with you. I could have provided more clarity and said this statement was directed toward the lyrical context of popular vocal music.

The general idea also applies to instrumental music.

It does not necessarily apply to all songs/music, or at least to the same degree. Not all music compositions have a melody or lyrics, and even if they have some sort of melody, they can be very subservient to the rhythmic function of the music.


One issue is that not all of us consider many words to mean the same thing.

The word "song," for example.

Merriam Websters

There exist relatively precise terms to express musical ideas. They are not very often used when discussing popular music in general conversations on most forums. That is a good thing from my perspective because I don't know what every one of the terms means.

Precision in written communications on forums rarely exists.

“Well…” Saint Peter, hesitated, “God’s got this girlfriend who thinks she can sing…”
