A good point regarding the Motown Chartbusters UK compilation lps I now they performed well on the UK charts [[ especially vol3)
Casual buyers get a full l.p. of hits by various artists instead of 1or 2 hits then fillers/covers
Also in the UK there was a mix price label called music for pleasure that released a 70s Supremes compilation called Stoned Love which included most of their hits a couple of duets and tracks from New Ways it was a really good buy from good old Woolworths
