So, once you’ve grabbed the client, you won’t need to insert a disk to start the game, it’ll just load directly from the XMB like the new Store, or, er, Home. You’ll still need your old disks if you want to sing along to any of the songs locked to the Blu-rays, but the client will obviously let you use your downloaded tracks.
Other features include the ability to cue up playlists with the Vita and there’ll be some demo tracks included in the free download. In addition to all this, if you’re playing single player you can now use the mic on the PlayStation Eye instead of the actual mics, and look out for new Trophies.
The SingStar client will be available to download soon.
