I know someone who met Tarja once, he said she was lovely.
Floor has that beautiful quality of being able to say something like "I am a great singer" and convey that she simply means it matter-of-factly, and she's not boasting or on an ego trip or something. It's a real European trait.
As for Tuomas' lyrics, well, I admire him for writing about different subjects and all, but the end result is often clumsy and clunky. I wouldn't call them neologisms so much as someone for whom English is a second language getting grammar and syntax wrong. I mean:
"At the end of the river the sun down beams
All the relics of a life long lived
Here, weary traveller rest your wand
Sleep the journey from your eyes"
The sun down beams? What does that mean? The sun beams down? The sunset is beaming? It just sounds wrong to a natural English speaker. Not criticising in any way, his English is better than my Finnish, but I would never hold that up as an example of a great lyric, and Nightwish are full of this sort of clunky grammar.
I'm off to lie down and sleep the journey from my eyes...
