Actually, I hear Nightwish have no idea but there are some songs from those that I like simple, and "Nemo" is one of them. I have the song for the first time in the season preview for the 5th season of "Charmed - Magical witches" heard and since then it has never left me. Since I did not want to spend for a single song Money for the whole album, I've brought the song as MP3 and packed to my player.
