Sony's President of Worldwide Studios Shuhei Yoshida has said the firm will "eventually" add MP3, music CD and DLNA server support to PS4.
"The biggest surprise for us all internally at Sony was; there were so many people who passionately reacted to our announcement that there's no MP3 support and DLNA support on day one," said Yoshida.
Some suggested the lack of music playback features was part of a ruse at Sony to drive subscriptions of its cloud music service, Music Unlimited, but Yoshida insisted this "it's not like that."
"Like we've been saying, the focus has been always on the game features, and some of the features we wanted but we could get in on day one - game features - we were very disappointed," he said.
"We didn't really think about MP3 or DLNA. We always thought that we're going to do that eventually - we've been doing it with all the [PlayStation] products. So it caught us off guard. People don't really talk about these features but when we say we don't have it some people get really mad and [say], 'I cancelled the pre-order'."
Yoshida went on to confirm, "So as we speak, the teams in Japan and US - the systems guys - are discussing how and when we can put these features on PS4."
Meanwhile, Sony has confirmed that PS4 users can overlay music on top of in-game audio using Music Unlimited.
PS4 is set for a launch date of November 15 in US and November 29 in Europe and Latin America.
