Song on my mind... "No Thinkin' Thing" by Trace Adkins

Forget mathematical equations
Self help psychology
Gray matter don't matter much darlin'
When it's gettin' down to you and me

This ain't no thinkin' thing, right brain, left brain
It goes a little deeper than that
It's a chemical, physical, emotional devotion
Passion that we can't hold back
There's nothin' that we need to analyze
There ain't no rhyme or reason why
'Cause this ain't, this ain't no thinkin' thing

This is what I get for listening to country music in the morning... again.
