And yes "Shattered Glass" is the ****ing pits. Circus is the only Britney album that I as a stan can say it has some trash. The rest of her discography is basically flawless.
It would have been great if this had been the track-listing:
1. Kill The Lights 2. Circus 3. Trouble 4. Phonography 5. Womanizer 6. Mannequin 7. If U Seek Amy 8. Blur 9. Amnesia 10. Unusual You 11. Radar
Just telling the truth Shattered glass is better than most songs on circus and yes people that say its bad don't know a quality song...unfortunately many Britney fans love bland generic songs instead of the real quality ones. I mean weren't fans shading slave for you yesterday
Love the intro.
