Way back in 1991 when I was just on to my second ever compact disc player I started collecting a series issued by Emi-Premier called "The Greatest Hits of" and these were from 1970 through 1980 and then just the 1981 and 1982 editions.
Reasons included having a single year focus which was rare and having a commentary on the year politically, culturally and so on which made for a package that took you back in time to that year.
At the time I was unaware that they had a Sixties series issued in 1990 run the same way as back in 1988 I had bought the odd disc of 50's hits in a Emi "The Hits of" series that gathered over twenty hits and served them up on the then new cd media.
In time I got some late 1960's volumes of the "The Hits of" series but that left me short on a good number of the others although I collected the "London-American" series that captured the American hits licensed from the late 1950's and early 1960's before many of the big labels established their own UK operations.
I have no got the 1960 through 1966 editions of "The Greatest Hits" that fill those gaps although I have a number of compilations that are not in a strict year sequence.
They have pictures of key artists and chart positions of songs which is always a good thing.
With spending time listening to things like vintage chart shows on Boom Radio, having my own copies of many of the featured hits is highly enjoyable as this was the music I heard on oldies shows when on the radio usually feeling poorly.
They do sound great.
