I'm attracted to the spongebob closing theme song?

Whenever I listen to the Spongebob closing theme song I used to get a really off feeling like something is not quite right, when I used to listen to it in my childhood at the end of the DVDs. Now listening to it again it brought back those unsettling feelings with a sense of nostalgia and comfort. These feelings combined makes me feel aroused, like an intimate and personal feeling, and I feel some resonance with the song. Because of this I listen to it many times throughout the day, I'm addicted to the feeling it gives me. I even designed a character based on the song credits.
