For me, an intro or theme song puts me in a mood based on my feeling for the show, or when I watched it (either place in life, or time of day).
The intro I watch from time to time is The Golden Girls. It just makes me relaxed and happy.
Game of Thrones also filled me with excitement when I watched it, and I loved the aesthetic.
MASH is another that I love.
And for pure nostalgia it's Leave it To Beaver and the Andy Griffith Show. Both were reruns in the morning when I was a kid and back to back. I would watch LITB then usually the theme of the AGS and go play.
