Check out the Donnas.

Also:

The Distillers
The Rag Dolls
Kelly Osbourne (first album only. Everyone hates it, but I don't think they've heard it. Great poppy/garagey/guitar rock)
The Muffs

Lovefool by The Cardigans should fit in perfectly

Velocity Girl could slip in there very easy.

Check out "Elevator Love Song" or "Ageless Beauty" from the Stars.

And don't shy away from Shakira's spanish records, they are all easily better than the english record she put out. In fact, her latest, Fijacion Oral vol.1 is her best record to date. So check out Obtener Un Si and Lo Imprescindible

Here's a few random suggestions not mentioned yet (both artists and songs/albums):

Lush: "Ladykillers", "Undertow"
Alanis Morrisette: Jagged Little Pill (you can't tell me you don't have this?)
Republica: "Ready to Go"
The Go-Gos: "Our Lips are Sealed", "We Got the Beat", "Vacation" (I think the first song will sound familiar)
Evanescence: Fallen
Concrete Blonde: Bloodletting, Mexican Moon
Heather Nova: Siren
Amanda Ghost: Ghost Stories
Hole

There are tons of others, especially if you go off into "Lilith Fair"-style folk-rockers, or 80s pop, classic rock, punk. There's lots of good suggestions here -- give some of these a shot and you might like something. Who knows, some of them may even be better than Hilary Duff?

If you like pixies: Breeders, Belly.

Track down a singer called Marisa Monte and find her version of Pale Blue Eyes. It's catchy in a good way

Judie Tzuke - Stay With Me 'til Dawn

I was going to suggest Republica as well. Rock/pop/dance mixed into one, without being annoying.

I'd suggest you pick up the best of collections of both Tori Amos and also the Cranberries, two of my favorite artists. I'm also a big fan of Chantal Kreviazuk and Natalie Imbruglia. You'll recognize Chantal's musical style since she wrote half of Avril's new album.

You might want to listen to the Go-Gos, you have a cover of one of their songs. Have you heard the original?

I think we're alone now - Tiffany (a cover of the '70s band The Rubinoos)
