I've been sitting on this news for a while since I didn't want to get any backlash from the corporate bigwigs... but the Flaming Lips are going to be in the new Sims Pets expansion. I've heard it and it sounds great. Great quote from Wayne:

"We've always been known to jump at opportunities that challenge us to do something totally fresh that we've never done. Needless to say, recording 'Free Radicals' in Simlish allowed us to do just that," said Flaming Lips front man Wayne Coyne.
