Yep, yep, yep! Mo-o-o-o surprised a thread like this has gone unnoticed!
The song I'm currently enjoying a lot by Diana Ross is "Chain Reaction"!
Quite underrated, it's a song made in 1985, 3 years before she releases a song we all know and love by heart.
The song was very successful mainly in Europe, scoring Top 10 in lots of countries, and peaking at #1 in the music charts of Australia, Ireland, and the United Kingdom notably. It did pretty poorly on the Billboard Hot 100 charts unfortunately, stalling at a peak of #66 and 11 weeks on the chart in total.
Fun Fact: Bee Gees actually wrote this song! And you can even hear their voices doing the chorus vocals near the end of the song.
And if any of you are curious,
here is a video I created 3 years ago that details the entire chart run of Diana Ross (includes her time in The Supremes) on the Billboard Hot 100, a United States music chart that catalogues the most popular singles each week, based on factors like sales and radio airplay. Nowadays it also includes streaming since that has grown a lot in prominence since the mid 2010s.
