That's interesting, I also read some of the previous editorials. Some of the criticism of bands "rehashing the formulas of the past" though (on editorial #4, which I agree with), comes less from a lack of ideological drive than from plain old lack-of-talent. I guess you could say their "unfocused" (hehe being kind) creativity is the result of ideological aimlessness, though.
Also, the idea that the "epic" and heroic traditions are the only worth writing about is limiting. On the other hand, there is a glut of self-indulgent introspection in songwriting these days, leading to the "everything is ok" standardless mentality that i think the author of those articles is really reacting against.
