Yes GGGB is a good album from #1 - #12. Even "HTILY" is growing on me.
Unfortunately "HTILY" I think is the last single. If she pulled a Gwen or a Nelly or a Bee I would say:
01. Umbrella (wish it could've helped the album more)
02. Shut Up & Drive
03. Don't Stop The Music
04. Hate That I Love You
05. Rehab (would be her "Say It Right" and would move sells in Xmas inflation)
06. Breakin' Dishes (would be HUGE pop hit)
