Can't get this melody out of my head!

My god, it's driving me nuts. I've only heard this song two or three times on the radio, mostly the tail end of it, and once on a car commercial but I don't remember which one. It's relatively new I think, only heard it over the last three or four months. It has a sort of techno beat with a woman singer and the only lyric I know for sure is that at a cretin point she screams "Sunshine" while maintaining a mellow tone for the rest of the song. I sort of know the melody but that really doesn't help me right now.

Does anyone know what song I'm talking about?

May be it? Thomas (Tomaz) and Filterhead - Sunshine

i have heard it too....hmmm

Thanks aljohnst but that's not the one. It's not so heavily teched as the song you linked and the one I have stuck in my head is also lyrical.
