i don't really like many of her album covers, i prefer her single covers.

I kind of...don't know. Haha.

In Driving Hit's, she looks so glamorous. That's one of my faves.
I guess I'll go with BEST ~second session~ cd only, which is the complete opposite of Driving Hit's. It's laidback, cute and random.
