MarketWatch reports on a Wall Street Journal article saying that Alain Levy, CEO of EMI Music, expects Apple to end the one-price-fits-all pricing in the iTunes Music Store within a year, increasing prices for popular songs and cutting prices for music by unknown artists. Levy reportedly discussed the issue with Steve Jobs, although the details of those discussions were not given and it was not claimed that Jobs made specific statements about iTMS pricing himself.
From a Levy press conference:
There is a common understanding that we will have to come to a variable pricing structure. The issue is when. There is a case for superstars to have a higher price.
