In height of her career Diana Ross released The Boss album and single in 1979. Ashford & Simpson worked their magic and Diana delivered some of the most amazing vocals ever. The single made it to #1 in Billboard Hot Dance Club Party and #12 in R'n'B but only #19 in Hot-100. Howver it's one of her signature songs, at least for this blogger. Love it more than I can say. David Morales remixed this in 1993 and Almighty in 2009 among others. In 1997 The Braxtons took the song back to #1 in Dance charts and #31 in the UK. The song hit the #1 in Dance charts again in 2008 by Kristine W ! The song was covered in her tour also by late Whitney Houston
