These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Covered Up: The Tremeloes' version of "Silence Is Golden" is considerably better known, as is the Walker Brothers' version of "The Sun Ain't Gonna Shine Anymore". The Spinners' version of "Working My Way Back To You" can be argued either way.
