Sony announced today at the Leipzig Games Convention 2008 that over 2.2 million SingStar songs have been downloaded via the aptly titled SingStore, which launched less than a year ago. Additionally, the company also unveiled SingStar Singalong with Disney for PlayStation 2, which as you might have guessed is a collection of Disney songs you can sing along to. Singalong with Disney is coming this Fall "exclusively for PAL territories." And hey, don't forget it'll be compatible with SingStar PS3.
