Rivals and customers of Vivendi's Universal Music Group were asked by European Union regulators whether the company's acquisition of EMI Group's recorded music business would allow it to increase prices.
Regulators in Brussels asked whether Apple's iTunes, the largest online music store, and others could prevent record labels from co-ordinating prices, according to a document seen by Bloomberg.
Regulators also asked whether online music retailers could succeed without songs from EMI, including the Beatles and Amy Winehouse; and Universal, which represents Lady Gaga and Rihanna.
Universal last week sought European Commission approval to buy EMI's recorded music operations, which develop artists and profit from recorded songs. Vivendi's Universal agreed to buy EMI's recorded music business last year for US$1.9 billion ($2.26 billion).
"Please explain whether, in your view, after the acquisition of EMI, Universal would have the ability to raise the price for its recorded music" for music bought online or offline, the EU asked in the questionnaire, which had a deadline of February 24 for replies.
