Hi mkbenn-
You don't have to use a thread label if one doesn't fit. Just leave that part blank if you cannot find an appropriate label.
I don't write songs. I only make up lyrics to annoy my children and grandchildren. Unfortunately, my children just get bored now, and I have only one granddaughter to annoy. She gets a rather heavy dose.
But I know what you mean. It often takes me several years to come to love a song well enough to want to make it part of my repertoire. I may not have liked the song at all at first, and I may well have forgotten and rediscovered it at a better time.
Joe
