For those who don't know, Meteor mandi, shower at Dawn (夜明けの流星群 Yoake no Ryuuseigun and can also be translated as Dawn of the Meteor Shower, which in my opinion sounds a lot lebih epic) is the song for Diancie and the Cocoon of Destruction. 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?...
