Ya, Dream Theater is definitely prog rock. The playlist is actually all symphonic rock/metal, I posted prog rock b/c that's pretty much the most popular form of prog right now, so that its ALMOST synonymous, Within Temptation, Evanescence (actually, probably more metal there), etc. But yeah, there is some prog rock I don't like.
BTW, the links I posted are symphonic rock, definitely. Meaning rock with a heavy classical influence. Frozen = Gothic Metal (subgenre of Symphonic Metal), Collide = Symphonic Rock, Rebirthing = Symphonic Rock.
So, I retract my statement and rephrase it to say "Symphonic," okay?
BTW: Kralik, I didn't like that one song, haven't heard much of their other stuff.
