4.0 - I never understood the hype until now. Thanks to this list, I now feel like I have enough context to get why people like this record so much. Having endured a sample of some of the schlock coming out in the 70s - e.g. terrible prog rock (Emerson, Lake and Palmer), lame easy-listening (Eagles), boring disco (Chic) - I can see how the Ramones redeemed mainstream music for so many. It's elemental pop music delivered fast and loud. All of the elements work. It's also just fun and perfectly captures teenage joy and angst.
