This makes interesting reading, especially in the 1960s section with the Motown entries.

I was pleased to see the Motown entries but surprised that the following very popular songs in the UK are not included:

I Heard It Through The Grapevine - Marvin Gaye
The Tears Of A Clown - Smokey and The Miracles
Baby Love - The Supremes
Upside Down - Diana Ross
I'm Still Waiting - Diana Ross
Dancing In The Street - Martha and The Vandellas
Being With You - Smokey Robinson
Endless Love - Diana Ross and Lionel Richie

Perhaps most people have bought the songs on albums and therefore don't stream them?
