Cover art for Happiness lyrics by Grant Lee Buffalo

I think he's saying that he's not an overly happy person, whereas the person it's aimed at is just one of those rose tinted glasses type that either don't see or ignore the world.

" Nevermind the songs they hum Don't want to sing along " Happy songs that there's nothing to relate to.

"There's nothin' that I said that'll bring you happiness" Is as Raffishtenant2 stated - his songs aren't going to solve your problem.

"Nevermind the words that came Out of my mouth when all that I could feel was pain" People say nasty things when hurt, especially in arguments when you say things you don't really mean.

" The difference in the two of us Comes down to the way You rise over things I just put down " This is how the other person just ignores things, that he can't.

"Nevermind the curse I wore Proud like a badge Till it just don't shine no more" How certain people will wear the bad things like a badge and break things. See Tool "The Grudge" for similar meaning on this bit.
