Record company Warner Music Group Corp. said Wednesday that its fiscal 2010 fourth-quarter loss widened on lower revenue, reflecting the continued shift from CD sales to digital music.

The company lost $46 million, or 31 cents per share, compared with a loss of $18 million, or 12 cents per share, during the same period a year prior. Revenue fell 13 percent to $752 million from $867 million. The fourth quarter ended Sept. 30.

Analysts surveyed by Thomson Reuters expected a loss of 13 cents per share on $731.7 million in revenue.

"The company's revenue results continue to reflect the transition from physical to digital in the recorded music industry where increases in digital revenue have not yet fully offset the declines in physical revenue," the company said in a statement.

Revenue from recorded music fell 13.3 percent to $619.9 million during the quarter, with the U.S., Japan, and most of Europe the weakest markets. But digital revenue from the sector rose 7 percent to $183 million.
