This is one of the best electropop song I've heard in 2005, and this new version surfaced just gave the proof that the song's still effectively awesome without the lyrics. So this is a track recorded for the soundtrack of The Sims 2: Nightlife game, so basically, it's the same song, the only change is that it was sung in Simlish, the language the characters in The Sims use to talk that makes absolutely no sense! You've probably heard another Simlish version of The Pussycat Dolls' 'Don't Cha' somewhere else. I'm not sure if Annie even re-recorded it, I think they just let it go through some kind of effect filter. Check it out anyway, it's fun.
