The deal is open to PS3 owners who haven't previously or aren't currently subscribed to the service. PS3 owners who accessed the free trial that came as part of the recent free PS+ membership offer are also not eligable.
To access Music Unlimited on PS3, just click on the icon in the music menu.
It is also accessible from Sony Ericsson's Xperia Arc and Xperia Play handsets.
The offer is limited to residents of the UK, France, Germany, Spain, Italy, Ireland, Australia and New Zealand.
