Can you guys help me understand part of Shakespeare's Sonnet 130? It's really confusing!?

My observation is that people tend to put those they are romantically involved with on pedestals, can't do wrong, Godly even. On the surface, she speaks the words I love to hear like a goddess but to be honest, music is more pleasing, while he has never seen a real goddess that must float rather than walk, his goddess walks on the ground. The humor may be in the fact we make others something they are not! Shakespeare probable had something else in mind but its what I see.
