Warner Music Group's total revenue in the second quarter, to March 31, 2010, was down 1.3% year-on-year to $662 million.

The decline was 6% on a constant currency basis. WMG said the performance reflected a light release schedulue, the continuing effect of a transition from physical to digital, and continued economic pressures affecting discretionary spending by retailers as well as a reduction of retail floor space dedicated to music.

Group digital revenue was $199 million (30.1% of total revenue), an increase of 15% from $173 million in the prior-year quarter. The constant currency increase was 11.8%.

Operating income grew 60% to $24 million from the prior-year quarter; operating income before depreciation and amortization (OIBDA) was up 8.8% to $87 million from Q2 in 2009. Net loss for the quarter was $25 million, or a loss of $0.17 per diluted share, compared with net loss of $68 million in the prior-year quarter.

"This quarter provided another example of our ability to generate stable results, even in the face of continued industry-wide pressures and a limited release schedule - delivering growing OIBDA with only moderate revenue declines," said Edgar Bronfman, Jr., Warner Music Group's chairman and CEO, in a statement.

"We remain on track to achieve our long-term financial and strategic goals, including driving free cash flow, developing innovative digital solutions, enhancing the value and growth of Warner/Chappell, investing in artist development and expanding our artist services business."

Steven Macri, WMG's EVP and CFO, said the major expects the 2010 release schedule "to be fourth-quarter weighted."
