Hymnody: The Easy 0/1 Tests

This is pretty good.

1. Good hymns focus on God; bad hymns focus on the self.

2. Good hymns use words and themes from Scripture or Tradition; bad hymns use words and themes from 1960s psychobabble

3. Good hymns treat transcendent concepts; bad hymns treat immanent concepts.

4. Good hymns employ sacred diction; bad hymns employ vulgar diction

There's plenty more at the link, here.
