Do toi think Christina Aguilera has gotten better ou worse over time?

I don't wanna use the word worse but the musique she's put out is definitely not as sensational as say... Beautiful ou Hurt.

Her voice is still the same greatness to me.

Personally, I think her voice gets stronger with every album.
We saw her true voice on Stripped, then even plus greatness on Back to Basics which btw in my opinion her voice was even plus powerful in. And I've heard the 18 tracks on Bionic, and I can honestly say I haven't noticed her voice declining..it just keeps getting better.

Bionic is epic <3! And 'You Lost Me' is one hell of a ballad!
