I love most of E=MC2!
Side Effects, IBLULT, For The Record, and I'm That Chick are the gems
And I commend the fact that she even tried doing songs like Cruise Control
Lord knows we needed a fun carefree album as a break after all that HOLLERING in Emancipation
I even use O.O.C. because I like how weird it is. The way the chorus ever so slightly builds up. It's a bop

I have to ignore the lyrics though
Love Story, Thanx For Nothin', and Bye Bye are rarely used by me though. Cute but completely useless. I use Last Kiss even though it's basically the same as the first two songs cuz it has that nostalgic factor
