Alanis Morissette, the edgy, rocker chick best known for her hit "You Oughta Know," has a pretty unusual and glum perspective on happiness.

"I think happiness is a state, and it's a temporary state," the singer told Oprah on an episode of "Super Soul Sunday." "So if we are chasing a temporary state, we're setting ourselves up to fail."

Morissette believes that other emotions, such as anger and sadness, are just as important as happiness. She stressed that it isn't "natural" for humans to just feel one emotion all the time. 

This isn't the first time she came forward publicly about her views.

She was also quoted in the book "The Little Book Of Happiness," published by The Next Big Think in 2010.

"I wish people could achieve what they think would bring them happiness in order for them to realize that that's not really what happiness is," Morissette said in the book.
