Lets start from the beginning.  Earlier stuff from NOFX such as Liberal Animation and Maximum Rock N' Roll, was hardcore.  The first few times listening to it made my ears cringe.  To be honest, they still do when I listen to them, which is rarely, if ever.  It sounded like a sloppy, garage band that just didn't care, which is the style I believe they were going for.  The guitar was way too distorted and the vocals just didn't belong.  Lets face it, if you weren't in the mood to break stuff and you actually listened to what Fat Mike sings about, you would be amazed at just how dumb the lyrics are.  Of course, I do give credit.   Everything that Fat Mike sings of is original and creative.  Also, the

Though the band has consisted of four members, they have never really touched upon a lot of guitar harmony before CD's such as S&M airlines, Ribbed, and The Longest Line, but when these CD's came out, they went from garage band to that great melodic punk sound, of the same time keeping their speed!  These too had clever lyrics and a not so cringing sound to it (that's a good thing).

Finally, everything else from then on was so spectacular that you can see a big difference from the beginning until now.  NOFX has left its mark on punk and still today makes it such a great style of music.  I am impressed and I give them all the credit in the world for everything they have done and all of their accomplishments.
