Digonex operates the patented DigitalOnlineExchange, described by the company as a “dynamic commerce engine” that helps companies determine the right prices for their wares by studying the marketplace. By gathering real-time sales data and analyzing purchasing data, Digonex says it can discover the pricing “sweet spot” satisfying vendors and customers alike.

The labels have expressed displeasure with iTunes ever since the recording industry realized Steve Jobs wasn’t joking when he said most individual tracks would cost 99 cents and most CDs would sell for $9.99. Lately the labels have wanted iTunes to allow for price changes reflecting consumer demand, charging customers more for popular tracks and less for songs barely moving off of the digital shelves.

Warner Music Group isn’t saying which artists, CDs or tracks will be used in the pilot program. Nor is the label saying which online music services might serve as a testing ground.

“Digonex’s technology provides us a unique window into one of the variables that impacts consumer behavior and by employing tools such as these we can continue to refine and improve our digital offerings,” said Larry Mattera, of WEA Corp, WMG’s U.S. sales and marketing company.
