What would you consider the best 3 songs to use to introduce someone to Babymetal?

I have plenty of friends whom I love sharing my love of Babymetal with. What would you consider as 3 great songs to get them interested? I'm thinking a song that touches on the more kawaii metal (get the initial shock out of the way) aspect that still has strong instrumentals to back it up as that's what got me interested. Then maybe a more recent song to display the band's growth over the years, and maybe an example of the variation of genres they dabble in. These are just ideas though, lemme know what you think is a good way to introduce Babymetal with the typical "three song trial."
