This is not the new song from Christina Aguilera but this is my favorite song. In this song she also play with Alicia Keys, a very talented R n B singer too. So, I think this song is very interesting because of the two wonderful singer play in a song.
In here,Aalicia Keys just play piano to accompany
Christina sing and make the music is better, and also give a little sound of backingvocals.
She just say a couple word in the beginning of the song to Christina as a song prolog at the same time she play the piano.
The music is very unique, because its also use trumpet.
Its like a mix of contemporer ...
