The European Commission asked Sony Corp. rivals and users if they think the Japanese company will use its greater market power for superior digital media deals after its acquisition of EMI Music Publishing, Reuters reported, citing a questionnaire sent to respondents.

The questionnaire reportedly includes how respondents think Sony will negotiate with those who collect royalties for artists and musicians and if the company will favor publishing over recording to drive revenues.

The antitrust regulator, which is expected to decide on the deal by Oct. 26, reportedly also asked about the potential impact of the transaction on online music streaming services.
