I've been listening to this album non-stop, for the most part, all month. If you've ever considered yourself an Avril fan, you need to get this. End of story.
With that being said, my least favorite track, as expected, is the single, What the Hell. It is to Goodbye Lullaby, as Sk8r Boi was to Let Go. However, the acoustic version rules! All in all, Goodbye Lullaby is an amazing album for any and all Avril fans.
Album of the yr.
... did I mention she covers Joan Jett at the end?
