I certainly appreciate what Harry and his team have offered us, and I hope for more because I enjoy what they've done. And I'll bet that Harry also wishes he could release many of the titles we request here.
If the Motown Select releases were big sellers, I guess we would see more [[they would hire more people if necessary). Universal Music is not a charity, and sales expectations must play a big role in the decisions as to what gets released. The Smokey Robinson Solo Albums series, for example, was halted due to poor sales. I'm very disappointed that this series didn't sell better [[I bought all the volumes) but that's the way it is and I understand.
Let's face it - unfortunately, there are not so many people today who want to go deep into the Motown catalogue. For most, a various artists / greatest hits compilation is enough, or perhaps a greatest hits compilation from one or more of their favourite Motown artists.
I would guess that the top selling artists for Motown Select would be The Jackson 5 / Michael Jackson, and Diana Ross & The Supremes / Diana Ross - and that's why we see more releases on them. Hip-O has already done several Diana Ross releases, so I guess these generally sold ok. They wouldn't have planned the release of "Baby, It's Me" unless they thought it would sell sufficiently. So I guess [[and hope) that this title is delayed for a reason other than sales expectations and will be released.
