Did the German Eurodance group Cascada ('Evacuate The Dancefloor', 'Everytime We Touch') totally rip off Katy Perry with their latest single 'San Francisco.' After listening, I would have to say the answer is, yes. This sounds like a terribly painful cheap cover of 'California Gurls.'

But don't take my word for it, you be the judge.
