Sony Worldwide Studios boss Shuhei Yoshida has said the firm will add MP3 and CD support to PlayStation 4 with a post-launch update.
Speaking in a recent episode of Giant Bomb's Interview Dumptruck, Yoshida said the firm never intended not to support either CD or MP3, but was surprised at the backlash received for not offering the functionality day-one.
"The biggest surprise for us all internally at Sony was there are so many people who passionately reacted to our announcement that there's no MP3 support or CD support on day one," he said. "It's not like we actively decided 'let's not do this feature so people will have to subscribe to Music Unlimited.
"The focus has been more on the game features. Some of the features we wanted but we couldn't get in on day one. We didn't really think about MP3 or CD. We thought 'we're going to do that eventually.'... It caught us off-guard.
"People don't really talk about these features, right? Some people get really mad and [say] 'I'll cancel my pre-order!' So as we speak, people in Japan - the system guys - are discussing when we can put these features in."
PS4 launches this Friday in North America and lands in Europe on November 29. A release window for the CD and MP3 patch was not provided.
