When a singer has a strong voice, you know she will endure. And that is what Christina Aguilera has done. This girl has a powerhouse of an instrument and I highly recommend her latest, Back to Basics. From the frolicky, pop-laden Ain’t No Other Man to the melodic Hurt to the bluesy, raunchy Mercy On Me, Xtina reminds us that no matter how many skanky Britneys or skanky disguised as angelic but with no voice Jessicas the music industry will feed us, when you got the talent you keep it.
