When SingStar made its PlayStation 3 debut and brought us the SingStore, we were all told that we'd never have to deal with "minor" SingStar releases again. New SingStar game out? You can bet it has some new features. SingStar 2 just barely squeaked by that criteria thanks to the new harmonies feature, but SingStar ABBA? I don't think most SingStar fans are going to want to let that one slide, and for good reason.
