Unknown female music artist

I’ve hear these songs: Viva la Vida (Coldplay), Bleeding Love (Leona Lewis), Please don’t stop the music (Rihanna) and one song of Kylie Minogue. All of those were sung by female artist in some kind of jazz/soul style. Who is that singer?
Thanks in advance

xA7XFanx,
None of these two is her. She is not singing only Viva la vida, she is singing plenty other popular songs but in her own style.
Mp3 King,
You did not understand my question. I am asking who is versifying all of those songs in 1st post. (i think versify means singing original songs in her own way).
hrykviop,
Nope, not The Bee Gees.

Can anyone else try helping?
I’ve also heard “Evacuate the dancefloor” by Cascade but sung by this female artist. It is beautiful but I just cant find out who she is.
