Speaking in Paris prior to Apple Expo Jobs said that he would resist demands from some of the world's leading music companies to raise prices because he believes that the move will increase piracy.
His comments come amid suggestions that some US labels are seeking a bigger share of the revenue from downloads on iTunes.
Apple's service currently has 82 per cent of the US market and charges 99 cents per download. UK users pay 79p (equating to $1.43) and the rest of Europe €1 (equating to $1.22).
Many music labels are said to be keen to use variable pricing on downloads as they do when selling through other channels. This would mean charging more for current music and less for back catalogue.
One label is said to have increased its wholesale prices but that iTunes has absorbed the cost rather than increased prices.
Steve Brazier, chief executive at analyst firm Canalys, said: "Apple is absolutely right. The industry has been revived and renewed by iTunes and it is far too early to think of price increases.
"I do not think that consumers will have much sympathy after the industry profited so much from the price of CDs in this country.
"Despite having a huge US share iTunes is in no way a monopoly. This is really about who has the power to control pricing. If a label drops off iTunes who does it really hurt?
"There is clearly waste and inefficiency in the industry and it is doing all it can to avoid doing something about it."
