Dream Theater is well known for being a mix of several distinct "styles". The four most prominent ones are: Metal, Progressive Rock, Melodic Rock and Pop rock. Each album has a good mix of each of the four styles, but there are some which feature more prominently than others. Here I've tried to map each album to the four styles.
The following is a table trying to describe each album according to this mix.
