Do आप think Christina Aguilera has gotten better या worse over time?

I don't wanna use the word worse but the संगीत she's put out is definitely not as sensational as say... Beautiful या 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 और greatness on Back to Basics which btw in my opinion her voice was even और 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 लॉस्ट Me' is one hell of a ballad!
