I don't know if everyone is aware, but there is a company called Hip-O-Select that has a Motown retrospective available for purchase. I believe it is a 12 volume set with each volume containing 120 songs give or take. The avenue they took was to begin with volume 1 & issue every single both A & B sides in chronological order, so that as you advance through the sets you also advance through the history of the company. Each set also includes a book with the background to each song as to who played on it etc. Pretty cool stuff for those that loved the music & the label.
