Apple has prevailed in the battle to maintain its one-size-fits-all iTunes pricing model, the Financial Times reports.

The company last night confirmed that all four major labels have renewed their US music distribution deal with iTunes, in which Apple will continue to sell songs for 99 cents each.

Sony/BMG, EMI, Warners and Universal are all understood to have agreed to maintain their existing arrangement with Apple.

The deals follow months of sometimes acrimonious bargaining between Apple and the labels. The labels wanted more control on price, a so-called "variable pricing model".

Speaking in September 2005, Apple CEO Steve Jobs called the labels attempt to change download pricing "greedy" and warned that higher prices would send users back to file-sharing.

Nielsen Soundscan reports that online music sales grew 194 per cent last year to 352 million songs, as overall album sales fell 3.9 per cent. Digital sales now account for about 5 per cent of major-label revenue, and Apple accounts for approximately 80 per cent of these sales.
