You don't hear so much about Mary Wells these days, but before Diana Ross came along she was pretty much the queen of Motown. The hits dried up when she left the label in 1964 and she died in 1992 at the age of 49.
This budget series Early Classics is a winner because with Tamla Motown, the earlier the better. All the hits are here, including My Guy, of course, and You Beat Me To The Punch, even a couple of duets with Marvin Gaye. The single Motown would have released if she hadn't quit the label is included (Whisper You Love Me Boy, later recorded by the Supremes) as are a couple of items that lay in the vaults for decades before having their day.
Two personal favourites are missing: When I'm Gone and What's Easy For Two Is So Hard For One, and a whole LP exists entitled Mary Wells Sings The Beatles, so I hope Spectrum put out a Volume 2
