LOL, good choice. Figured out the double entendre yet? "The End of This Chapter" by Sonata Arctica Sonata Arctica is always a good option for the obsessed / "devoted."
"Rose of Sharon" by Killswitch Engage The song sounds really rough and angry because Killswitch's lyrics are usually screamed, but I love how all of their songs have an upbeat message even in the worst of times. The lyrics put a twist to a loved one's death. Instead of being sad that he's lost her, he knows he'll see her again; and instead he mourns for those who never got to know her in life.
The Heaviest Matter of the Universe by Gojira. The title says it all. Heavy as God's hand on the heads of the wicked.
"Intensity in Ten Cities" by Chiodos I'm not the one that you want; I'll only let you down, and I'm pretty sure that you've caught on. And you can say that oh, I'm just feeling sorry for myself... Kind of makes me want to go jump off a cliff. But it's good for the mood I'm in.
