SEOUL, South Korea's broadcasting watchdog chief said Monday that authorities are looking into whether Apple Inc. is making excessive commission through its App Store.

Some lawmakers have alledged that users have to pay an extra 8,000 won (US$7) in commission when using the music streaming service Melon through the U.S. tech company's App Store.

"We will thoroughly look into the case," Lee Hyo-seong, chairman of the Korea Communications Commission (KCC), said during a parliamentary audit. "I believe such a thing should not happen."

Apple is not properly notifying users that they do not have to pay the extra commission when purchasing a Melon unlimited streaming pass on a computer, Rep. Kim Sung-soo claimed.

Melon, a business arm of Kakao Corp., is the industry leader and currently accounts for 50 percent of the country's music streaming market. Melon secured an extra 130,000 users during the second quarter.
