Eh.

I think this [url=https://www.youtube.com/watch?v=sMXjtvMAFlI]one[/url] takes the cake. 

Although not the actual show's theme, this [url=https://www.youtube.com/watch?v=Sjq1RH9nh7g]one[/url] gets major credit in my opinion for combining the two series' themes together.

I like those too, but I consider them more theme music/tunes than theme song.
