Ah, Nightwish hasn't offered too much of anything that hasn't been heard anywhere else. It's repetitive and trying too hard to be "epic", not in a good way, but in a pretentious teenager way. You're better off with Therion.
There's no earthly way of knowing which direction we are going. There's no knowing where we're rowing or which way the river's flowing. Is it raining? Is it snowing? Is a hurricane a-blowing? Not a speck of light is showing, so the danger must be growing. Are the fires of hell a-glowing? Is the grisly reaper mowing? Yes, the danger must be growing 'cause the rowers keep on rowing, and they're certainly not showing any signs that they are slowing. AAAGGHHH!!!
