I think that's what the Prodigy have foudn tbh. Their popularity was waning until Firestarter came out, totally shocked people, and threw them back into the limelight. That's all well and good, but now they have to always have Keith yelling and shouting on their records, or people will lose interest. That's what they have come to expect from The Prodigy. The new album has a much more old skool ravey sound to it (like Experience) but they still had to include the token shouting on their tracks, as that's what people expect from them. It got them a huge amount of popularity and attention, but has now totally typecast them and restricted them. Double-edged sword!
