From an average listener's point of view, comments about the song by the author would probably have effect on whether or not I liked it. From the point of view of a singer looking for good songs, I'd have to see what the song is or can be on its own and whether that song - and nothing but the song - says something I want to express. But that's a whole nother thread topic!
