The Open Door is much darker than Evanescence's previous album, Fallen. Most of the songs are about Amy Lee's break-ups with Ben Moody (who abandoned the band on top of it all) and Shaun Morgan ("Call Me When You're Sober").
"Lithium" uses the idea of being "addicted" to the person in the relationship as being similar to a drug addiction (at least, that's what I see in it). "Snow White Queen" is about being stalked and/or raped. Not truely graphic, but haunting. "Lose Control" is obviously about wanting to throw self-control to the wind and. . . you get the picture. It isn't graphic in any sence. "Like You" is a very saddening song, and like "Hello," for Fallen, it's about her late sister, Bonnie. Those are the only songs I can think of that people might have issues with. And if they have issues with Evanescence. . . there must be something wrong with them. ;-)
I love "Good Enough." Amy wrote this song about her husband (then friend/boyfriend), and is about her finally feeling good enough for him to love her. Personally, it makes me feel confident that I'm good enough for the ones I love as well.
Amy's vocals are hauntingly beautiful. It's a dark album, and for some, it's depressing, but I think it's just as much a masterpiece as the Fallen, if not more so.
