I spent a lot of time trying not to do voices like mine. The voices on "Karma Police", "Paranoid Android" and "Climbing Up the Walls" are all different personas. I think "Lucky", the lyric and the way it's sung, is really positive, really exciting. "No Surprises" is someone who's trying hard to keep it together but can't. "Electioneering" is a preacher ranting in front of a bank of microphones.
