This CD was released in the very earliest days of digital technology. It is long out of print, and has been replaced by better Supremes compilations. All the songs here are terrific (and in stereo). There are a few big hits missing, though, the most notable being the Number One hit "The Happening" (which is admittedly the weakest of their Number One hits). Although there are better Supremes compilations currently available, this CD is worth acquiring, if you can find a cheap used copy of it.
