I only heard the single "Bring me to life", which is quite nice. Actually it sounds like a Linkin' Park copy, but with a female vocalist. I did read that this isn't the case with the rest of the album though, which is probably a good thing.
I've actually met them once, when they were promoting their album in Holland. A friend of mine did a short interview with them for his radioshow.
Oh! I started to really like them after I saw this music video someone made of Final Fantasy X-2 with Evanescence's Whisper. Thats a great song! I like this other one but I don't know the title. I'll try to look for it (title of the song).
