Songwriting on an Island

So you're stranded out there somewhere, and you're writing songs, but there's one problem: There's no one to give you any real constructive criticism or help. Now, I’m not talking about friends and family listening, then telling you are great and they are oh so proud. I’m talking about someone to tell you when that verse section goes on too long, or when the hook just isn't hooky enough, or that this one is just okay, and maybe you should ditch this idea for now and work on another.
