NW at its best!

When I first heard of Floor replacing Tarja/Anette my first thought was;
how are they gonna pull this off?!
How are Bless the Child or Amaranth going to sound with the singer of After Forever...?
Answer: Floor made the songs her own with no disrespect to her predecessors.
I don't think Tarja Could've pulled off Endless forms like Floor did.
Any thoughts anyone?
