Nightcore Recommendation?

[NightcoreCX]

Hello! I am looking for new Nightcore songs to add to my playlist.
I really like sort of darkish songs. For example, Dollhouse by Melanie Martinez, It's Been So Long by the Living Tombstone, and Secrets by... Well, I forgot the band name, sorry =P
I also LOVE war songs and epic songs, like Phoenix by Fall Out Boy and Warrior by (dangit, also forgot the name of the band!) >.< Courtesy Call By Thousand Foot Krutch is currently my favorite song if that gives you an idea of where I am headed.
So yeah, something pretty epic and maybe dark. I appreciate all suggestions, and don't be afraid to suggest! You could be saving my music life by suggesting! =P
