Catchiest Theme Song?

So out of all the seasons, which theme song is the most catchiest in your opinion? It's a tie between the Mighty Morphin Power Rangers and Lightspeed Rescue theme song for me. While it's been quite a long time since I've sat down and watched Lightspeed Rescue, I still get the theme song stuck in my head from time to time. xD (I'm in the process of re-watching all the seasons, starting with the Mighty Morphin Power Rangers. xD) Because I'm re-watching all the seasons, the MMPR theme song gets stuck in my head a lot too.
