What is this song's name?

I cant quite remember the lyrics but all I know is that it was sung by Gwen Stefani.. It's definitely not "Just A Girl", "It's My Life", or "Underneath It All". I've heard those songs shopping on separate occasions though. :P
I dont know this helps but the chorus goes follows this chord pattern (posting in C major for simplicity) C Am F G.
Any and all suggestions are welcome, thank you!

There were a lot of No Doubt / Gwen Stefani songs played at Kohl's. You can look these up and let us know what you find.

"Don't Speak"
"Running"
"4 In The Morning"
"Simple Kind Of Life"
"Hey Baby"
"Hella Good"
"Cool"
"Sweet Escape"
"Hollaback Girl"
"Rich Girl"
"Southside" (with Moby)

"Settle Down" (the latest song)

Hmm, it's definitely not any of those but I do think it sounds a bit like "Running".

Okay, so you're looking for a song that sounds a bit like "Running". How long ago did you hear it? Are there any other details about the song that you can remember?
Here's one song from a few years ago that fits the category:

"Lovefool" by The Cardigans
