...in the ol' classic 60s/70s soul/r'n'b area. I was ripping my CDs to my iTunes and noticed an alarming lack of such music. So I was just wondering if anyone here could point me in the direction of some of the greats.

I'll tell what I've got already;

The Isley Brothers - [some cheap best of comp or other]
Sam & Dave - The Best Of...
The Golden Torch Comp.
The Temptations - My Girl
Diana Ross & the Supremes - Singles Collection
Barry White - Singles Collection

And it's only the top four albums there I still listen to on a regular basis.

Any pointers would be muchly appreciated
