Dream x Arlin
Smile by Avril Lavigne
Says bad words! It says "You know that I'm a crazy b*****, Do what I want when I feel like it. But you don't really give a sh***!"

Another Dream x Arlin
Baby Blue Eyes by Rocket to the Moon (?)
This is because they both have light blue eyes XD

Dream and Arlin's backstories!
Jar of Hearts

Last one... I think this one does not match well but here!
Light em' Up!
