well, one that immediately comes to mind recently is Micheal Jackson's "Working Day & Night" of the "Off the Wall" album..I live in NYC & with all that's going on, people are still doing their thang..I happened to be playing this song on my CD walkman one morning...& just walking in that crowd of people who are determined to go on with their lives while listening to that song just energized me! I almost started crying...
some others are:
Black Butterfly-Deniece Williams
Get Up-Amel Larrieux
Dream on Dreamer-Brand New Heavies
Day Break-Brand New Heavies
Stormy Weather-Lena Horne
I Got Rhythm-Lena Horne
Give it Up, Turn it Loose-Envogue (when I broke up with my cheating @$$ man)
I have way more than 8, really, but will just stop here!
