I only realised, a little while ago, that my two favourite songs from the Contemporary age (for me, at 69, anything after the sixties is contemporary) were both sung by Whitney Houston.
This video of a song was one of those adopted by the 1988 Seoul summer Olympics on their CD of music of the games. It is called One Moment in Time and although showing the dedication of an Olympic participant, I would think it might have also been an example of her own dedication of reaching the top of her profession. Enjoy:
Apart from the singing, the music, in the middle, is lovely.
