Sony Corp.'s music operations -- which consist of three separate companies, Sony Music Entertainment, Sony/ATV Music Publishing and Sony Music Entertainment (Japan) -- experienced a drop in sales and income as the music category posted 7.3 billion yen ($91.8 million) in operating incomes on 98.8 billion yen ($1.24 billion) in sales for the company's fiscal first quarter ended June 30.

That's a 39.6% decline in profit from the 12.1 billion yen ($152.1 million) the company posted in the first quarter of 2011, when sales were 109.6 billion yen ($1.38 billion).

Sony attributed the drop in sales and profit to a slower-than-2011 release schedule in the Japan music operation, and to the over decline in CD sales. It also said that the 2011 income total was inflated due to a favorable U.S. legal settlement concerning copyright infringement.

During the first quarter, Sony's best-selling titles included One Direction's "Up All Night-The Live Tour DVD;" Carrie Underwood's "Blown Away; and Usher's "Looking 4 Myself."

The company also noted that Sony Corp. of America-led consortium had completed a significant acquisition of EMI Music Publishing, with Sony contributing $320 million toward the $2.2 billion acquisition price to garner a nearly 40% share in EMI Music Publishing.
