Cover art for Caribou lyrics by Pixies

First, to the person who posted that Smells Like Teen Spirit was patterned after Gouge Away, it was (per Cobain) patterned after U-Mass. Listen to both, the similarities are striking.

About Caribou, I think it is clearly about reincarnation.

I live cement, I hate this street, Give dirt to me.
(this life sucks, wish i were dead)

This human form, Where I was born, I now repent. (i was born human, but i wish i weren't)

Caribou (my choice for my next form)

Give me white, Ground to run, And foregone. (carefree life of animal, nothing is expected)

Lets me knife, Knife me lets, I will get What I like (either the knife will get me or i will get the knife (suicide)) (either way, i will get what i like (death))
