@Tboy Howdy! One way of looking at this can be as such.
Your music, can be centered around timeless principles and wisdom of reality, your personal perspective on it. to create groundbreaking music means digging where others haven't, or where others have given up, but what you dig up is your life purpose, not you. if you are 80, and still creating music that is based in truth, there will always be an audience for it.
I keep stumbling on songs from the 70'sto early 2000's and because of the content of the song, I resonate with it.
Not sure if this helps, good luck!
