R&B boxsets....Atlantic,stax,motown,etc....

which one is the best?
Hard question to answer. Depends on what style of R&B/soul and which label you like best. Personally, I'm partial to Stax. Years back, they released two box sets called the "Complete Singles." Each set contained 10 CDs. I have the one that covers 1959-1968, and it's incredible.
