Hmm...but it'll surely be fun to be at her concert! I have all 3 of her albums: Let Go, Under My Skin, and The Best Damn Thing. My favourite album would be her first one, Let Go but the others aren't that bad either.
Sigh...why would some people protest against her concert??? It's just music and her songs are great. Well, some are really angsty but still, it's good to listen when you wanna release your anger. Haha!
Anyway, check out this piece of news and the comments underneath. They're so funny.
ETA: This article is even funnier!
