The thing is Ron, it has always been true that most of the stuff recorded never gets heard. Most of the songs that get written are never sung, never played, never recorded, and maybe even never make it off the page they were written on--for every 10,000 songs written, maybe one becomes a page in the Great Songbook, and maybe not even that--

The thing is, all those forgetable recordings are part of the process--even the best songwriters have a fairly high ratio of misses to hits--

You work on your craft by writing songs, and by trying to get them heard. That's it. You give em them best you've got--if that's not good enough, so be it. Can Ron Olesko give a songwriter a formula for determining which songs to push and which to throw out? And if he could, would he be right?
Nobody knows what's going to go over and what isn't--that's why you're "advice" is way off the mark.
