Alanis Morissette celebrates her birthday this weekend, but perhaps one of her greatest gifts to the world was a little album entitled Jagged Little Pill. Everyone had a copy of this album when it was released, here are nine reasons why you had to own it.

1. Because everyone else had it

Literally, the entire school had a copy of this album. You had to, it was like an initiation.

2. You wanted to learn how to play the harmonica

And clearly Alanis Morissette was going to teach us how to play...

3. There was a woman cursing on a song

On the You Oughta Know track, Morissette screams "are you thinking of me when you fuck her" and you always took immense pleasure in singing along to that. Despite the fact that you were thirteen...

4. There were plenty of life lessons.

You live, you learn. You love, you learn. Profound. Absolutely profound.

5. Head Over Feet

This track just described all of the relationship you had up to that point. We mean relationship, the one where you kissed that guy at the back of the school yard "you've already won me over..."

6. Scoff at Ironic

It's a coincidence Alanis, not ironic. Silly girl.

7. Stick it to the man

Essentially, stick it to your parents. I'm not Perfect Mom and Dad. I'm not perfect! Alanis said so!

8. Confuse us about religion

"You know how us Catholic girls can be..." No, what do you mean Alanis?

9. That secret track

Oh, that moment when you realised she had hidden a track on the album. 13 screaming, wailing tracks for the price of 12.
