What songs do you consider to be "related"?

I thought it would be fun to see what Taylor songs might be "related" to each other. For example, I always thought of Sparks Fly and Fearless to be twin songs - both talk about kissing/dancing in the rain and the feeling of falling for someone - I have always associated them in my mind.

TLGAD could be the cool aunt of TIWWCHNT, and of course Maroon is the older sister for Red. What other songs do you feel could be related?
