Take the Time and Under a Glass Moon are awesome tracks off that album as well. - Edit 1

Dream Theater - Pull Me Under - How could I have never heard this song before this morning? Or heard of this group? I know that I would have noticed if I had even heard any part of it before. Maybe the radio stations in my town assume nobody is going to like that kind of music. But I am not "nobody".
I've been out exploring for "similar artists" to other bands I like a lot here lately. Last.fm is a great site in terms of recommending similar artists. you might want to check that out.
I tend to lean towards the more metal side of things. Found Symphony X, as you mentioned earlier, and Mercenary with similar sounds to DT. Mercenary is heavier, but I'm liking it. Architect of Lies is an awesome album.
Even heavier, Scar Symmetry, is a great band. That might be a bit farther out for you though.
