What is worldly music?

In my understanding, worldly music is pleasant to body and mind (has pleasant words), but it is not pleasing to the Lord

The Lord does not accept that man is exalted, but only that God be forever exalted.

Worldly music doesn’t have the power to transform the human heart–we remain the same people full of sin and lust after the song.  It does not call us to repentance of sin nor reverence toward God.
