Just something random I came up with. Just pick a song, and make a Pure Light Version of it. For example, Ghost Division by Sabaton. Here:
Fast as the wind, the Invasion has begun! Shaking the Ground, with a force of thousand talons!
First into the Line of Fire! First into Hostile Land! Elites leading the Way! Leading the Way!
Charging the Lines, With the force of a Furious Storm! Fast as the Lightning, Alphas Swarm!
200 Miles at Nightfall, Taken with a Day! Thus earning the Name, earning the Fame!
They are the Darker Elite! Born to Compete! Never Retreat!
Dark Division!
Always Ahead! Living or Dead! Fed by your Dread!
See what I mean?
