Some days I’m a super bitch! Oh no, not me. I’m just singing along with Christina Aguilera’s new single, “Keeps Gettin’ Better,” which finds the bleach-blonde diva traveling away from the big-band sounds of Back to Basics, and toward an equally delectable (and appropriate) electronica vibe. That throbbing synth line is guaranteed to turn any sidewalk into your own personal outer-space-themed runway — come on, it’s not just me. Right? — and that’s why it’s on my Must List right this very minute.
