Actually, I'm not counting Power of NEO as the second theme-It's the same letmotif as Battle Against a True Hero. Only unique letmotifs are counted.

I'm counting Metal Crusher (used for the quiz and his battle after the tile puzzle), and It's Showtime (used when he first appears, and Death By Glamour, his EX theme, used this letmotif)

THESE are two unique letmotifs for Mettaton. So, like I said before, if Mettaton can have two themes, why can't Sans?
