Sony has bought its Music Unlimited subscription service to the Walkman range of portable media players.
The service, available for the PMPs as an update, gives users access to a 10 million song music library with two content sources, Channels and My Library.
The Channels section features radio-like collections based on era and genre, while the My Library section allows users to sync music to their devices.
Unlike traditional, cloud based music locker services, however, users won't have wireless access to music. Instead, they will have to connect their players to their PCs to transfer content.
The company said service comes with a free 30-day trial after which it will cost $9.99 per month. Sony stated the Music Unlimited platform is available for the NWZ-A860, NWZ-S760, and NWZ-E460 series Walkman portable media players, as reported by CNET.
"Sony Entertainment Network's Music Unlimited service features an ever expanding global catalogue of over 10 million licensed songs and is currently available in nine countries including Australia, France, Germany, Ireland, Italy, New Zealand, Spain, United Kingdom, and United States," said Sony in a statement.
