By the way, there's a Swedish "ambient" band/musician that goes under the name "Sephiroth". Yes, I'm aware that it's not an original name from the game but most people probably connect it to the game character anyway.
There are many bands with names that appear in Final Fantasy. Of course they were not chosen because of Final Fantasy, but for their history/meaning.
Examples:
Ragnarok
Behemoth
Tiamat
