Great band...great album. Totally disagree that it gets too much importance tagged to it or to punk in general. Like it or not, rock music was drastically reshaped by punk and it continues to be a strong influence today. The post-punk stuff in the 80s was a direct outgrowth of it, the grunge of the 90s was highly influenced by it and even the garage rock stuff that has been quite popular this decade is influenced strongly by it. The DIY business model that grew from punk influenced the whole indie movement. Even punk style has become a staple with a black leather jacket hanging in even the most conservative of closets.

I can see why you may have issue with the album or the genre from a personal taste point of view...althogugh it is one of my favorite albums of all time that I can listen to again and again But, denying that punk changed rock music deeply and permanently just doesn't really seem very plausable to me.
