Warner Music Group during its fiscal results call today acknowledged that its digital music sales have slowed since it helped push for variable pricing on iTunes last year. In the fall, the company's digital sales equivalent to whole albums grew about 5 percent compared to late 2008 where it grew 10 percent over this past summer and 11 percent in the spring. Absolute digital revenue followed a similar pattern as the income grew 8 percent year-over-year in late 2009, but less than half the 20 percent from the end of 2008.
