The provided article text for this Louder Sound piece consists almost entirely of website navigation, membership sign-up prompts and newsletter promotions, with no actual ranking or discussion of Dream Theater's albums included. As a result, it is not possible to produce an accurate summary of the album rankings, critical assessments, or reasoning the article presumably contains, since that content was not present in the text supplied.

To provide a meaningful summary of "Every Dream Theater album, ranked from worst to best", the full article body—including the actual list of albums, their positions in the ranking, and any accompanying commentary—would need to be retrieved from the source page.
