Apple's Steve Jobs is resisting attempts from the music industry to raise the price of tracks in the iTunes Music Store.

With the licensing agreement between Apple and the record companies due to expire early next year, the music industry is keen for Apple to introduce flexible prices into their iTunes Music Store.

Currently all songs cost 99 cents and albums $9.99 in the US, but Warner Music Group's chief executive Edgar Bronfman feels this needs to change.

"There's no content in the world that has doesn't have some price flexibility," Bronfman says. "Not all songs are created equal. Not all albums are created equal."

While the record companies insist many songs will be cheaper than 99 cents, many feel that the move is an attempt to raise prices.

Chief executive of Apple Steve Jobs is continuing to insist on fixed prices for simplicity. "Music companies make more money when they sell a song on iTunes than when they sell a CD," he says. "If they want to raise prices, it's because they're greedy. If the price goes up, people will turn back to piracy. Everybody loses."

The iTunes Music Store is widely regarded as having legitimised music downloads but the music companies are now suspicious of their large market share.

Apple has sold more than 500 million songs through the iTunes Music Store. The service accounts for 82 percent of all legally downloaded music in the United States, and 70% worldwide.
