Matt and Andrew's CD a Day project

What can you say about this one that hasn't already been said? My buddy Andy and I used to pop a cassette of Nevermind into his Ford Tempo in high school and then head-bang in unison to Dave Grohl's intro fill. Yeah, we were dorks.
13 years after this came out, it still sounds fresh. Is that because it's timeless, or because bands like Smile Empty Soul are still ripping off Nevermind? Sound off on our messageboard.
