I am not familiar with the specific articles and songs raised in the OP. I may try to give 'em a listen. Without knowing the motivation that is implicit or revealed by the originator of the songs and lyrics, it can range from Allan Sherman style 'clever' 'humorous' to 'socially responsible'. And the appropriateness and aptness of the lyrics will weigh on of themselves.

Let us remember that the American popular song "Yankee Doodle" was an adaptation of very clever lyrics written by an English attempt to make fun of New England Americans, itself a very funny song and fun to sing, but almost unknown among the Americans of today.
