Happy:

The Purple Bottle - Animal Collective

It makes me think about some retarded person skipping merrily through the jungle, singing a little jingle even, and a blood thirst tiger running relentlessly after him.


Sad:

Sierra - Cursive

How can a highly detailed admittance to why your wife left you and you've lost contact with your child, but you want it all back, not make you sad.


Thinker:

Let's Not Shit Ourselves (to love or to be loved) - Bright Eyes

A ten minute story starting with a perception on the world, and ending with a new one. The story between describes all the awful, and good, of the world. "How greatful I was then to be part of the mystery, to love and to be loved. Let's just hope that is enough." The final line of the song, summing up the entirety of the message.
