The service is already available on PlayStation 3.

“We will make [an NGP version] happen. Our services need to be available on that device. It’s a very powerful device and it would be an incredibly good platform for us,” Sony Network Entertainment CEO Shawn Layden told Eurogamer.

Music Unlimited is, of course, part of Sony's plan to tie all its major consumer electronics devices together. If you have a subscription with the service, you can theoretically access on-demand music from your PSP, PS3, Blu-ray player, computer and more.

“You can see that in the gaming world, because you can pull down PSP games across a PS3 and associate that with your portable player. You can create your account in your country home on your PS3 and access the same content you purchase on your other PS3 home. Associated sharing is already happening.

“What we’re trying to do at Sony Network Entertainment is bring all those different content domains into a more comprehensive space for the user, so you don’t have to go chasing around in three or four different directions to find that,” he said.

“If we can bring it all together with one wallet, one sign in, one password, and give you access to music, movies, games etc, that’s a better value proposition for the user.”
