Some people use the word, 'wisdom '. So in our case it would be called 'songwriting wisdom'. But still, no matter how much wisdom someone writes down for someone else, it can't be transmitted perfectly to a reader. Like planting a seed. Both knowledge and wisdom are essential.
Some people get tons of wisdom without much knowledge.
Others have tons of knowledge and no wisdom to use it. I get so sad watching songwriters that I like to support, get themselves sidetracked into the halls of head-knowledge. They start getting farther from their goals and they are clueless as to what went wrong. It really saddens me. Please don't let this be you.
