Remember the Golden Rule

More to the point - what makes a good audien (sic) for it is the receiver of a song that declares it a good song. The songwriter who declares his song good still has to run the gauntlet and he has chosen a large gauntlet by declaring.

Maybe we know a bad song when we hear it - moreso.

Horses for courses definitely. Bad songs can be bad in the way that makes them good fun. see Golden Rule
