Sony has released its “Music Unlimited” app for iPhone, iPod Touch and iPad which would enable you to savor high-quality tracks on the go. As of now, the app is limited to New Zealand app store though I am sure other Sony Music Unlimited countries would get the app soon. In order to listen to millions of songs on your iDevice, you’d have to download the free and subscribe to Sony’s services which costs $4 per month. You would also be able to sync your music with your Mac or Windows computers via Music Sync service. This feature sounds really cool to me, I guess other such services would have to buckle up in order to survive against Sony’s excellent collect of music.
