Help with AE song from June 08

Would someone please help me identify a band played in AE stores? The band had a girl lead singer with long platinum blonde hair. The video played right before The Kooks "Always Where I need to Be" I wrote it down on a card and now can't find the card. I thought the name was Dark Horse, but when I type that in a search engine, it doesn't come up. Thanks for your help.

It's the Duke Spirit
