mad of not finding that song :) medium husky female vocal soul house music!

singing in spanish, song starts in few first seconds, released before 2006, but after 2000 i guess! the thing is that it is unbelieveble beautiful melody, you can hear rhythm and beat but its very soft and voice is quiet, no any: nananan, ohohoh.. just beautiful quiet voice, strong melody and background beats!! people, i am wondering why that song doesn't became a second besame mucho!? very powerful melody, makes me cry even
please help! i will payback )

okay, its like dj version of the song "let the sunshine in.." if it's low tempo and quiet beat and quiet voice, it's like jimmy sommerville "something to live for" extended mix 1999. the song i am looking for are similar to those two, especialy to "something to live for" extended mix! same tempo of the drum but completly different melody!
