It's tricky to review this one out of context of the whole 'Complete Singles' set, but after the relatively weak showing of the 1971 sets, which were padded out with a lot of very weak songs, this one has some definite 'name' hits that are great second-tier Motown classics if not outright standards (and to my ears second division Motown is about as good as most labels' top works). By now they'd scaled back from the experimental subsidiaries that marred the earlier volumes, and though there's still some acid-rock tracks from the Rare Earth offshoot, it's mostly just good pop-soul music in the magic Motown mould.
A Simple Game, Rockin' Robin, Superwoman, Walk In The Night are all pure classics. There's a bit of duplication with the promo mixes (which don't hold much appeal for me as they're not *that* different), and a few covers of old Motown songs that have been retooled for a 70s audience (Blinky's version of Motown's first hit Money (That's What I Want) is great, The Undisputed Truth's Papa Was Rollin' Stone and Edwin Starr's Ball Of Confusion less so), but also a lot of undiscovered gems that are sorely overlooked; Syreeta's To Know You Is To Love You is a Stevie Wonder song in all but name (he even sings on it), and Chris Holland & T-Bone's Get Me Some Help is one of the few examples of Motown's Rare Earth subsidiary indulging in some baroque-pop even if the vocal is a love-it-or-hate-it affair (I veer between the two).
If you don't have any of the previous sets, then this on its own is not going to make much sense, so would advise caution and start with the The Complete Motown Singles, Vol. 6: 1966 which is the label's high watermark. For everyone else who has the previous volumes, this is a worthwhile addition (if not quite worth the four-year wait between this and the previous volume) and a fine way to approach the final months of this historic document.
