The Japanese name for Diancie and the Cocoon of Destruction is The Cocoon of Destruction and Diancie (Hakai no Mayu to Diancie)
For those who don't know, Meteor mandi, shower at Dawn is the song for Diancie and the Cocoon of Destruction (Pokémon the Movie 17). anda can listen to it
link, but it's only in Japanese.
Of course Meteor mandi, shower at Dawn might not be the English name. Japanese pokemon movie songs tend to be named after the first words in the song, and one of the first words is
yoake (dawn). But as many of us know English songs aren't usually like that.
Lyrics:
Yoake mae fukiareta kaze wa nanno maebure?
Uso de katameta HAATO hagare ochiteku
Nakanai to yakusoku shita no ni tomaranai SUKOORU
Kimi no koe ga fui ni kikoeta...
