I know there are a few of us that like this style of music (Norman, Hennuli). There are the big groups like Nightwish, Lacuna Coil, and Within Temptation, but there are some I don't hear about very much that I wanted to share with you. Also, if you know of some, definitely put them here!

Some of my favorite "lesser-known" groups:

Leaves' Eyes (Germany) - featuring Liv Kristine (formerly of Theatre of Tragedy) - Myspace
After Forever (Netherlands) - featuring Floor Jansen - Myspace
Epica (Netherlands) - featuring Simone Simons - Myspace
Xandria (Germany) - featuring Lisa Middelhauve - Myspace
Lullacry (Finland) - featuring Tanja Lainio - Myspace
Elis - (Liechtenstein) - featuring Sabine Dünser (deceased) - Myspace
The Gathering (Netherlands) - featuring Anneke van Giersbergen - Myspace

Yep, very nice groups ^^
I´d like to add another one, which is also lesser-known:

Flowing Tears (Germany) formerly known as "Flowing Tears and Withered Flowers"
