Under My Skin

Sebagian besar lagunya direkam di Maida Malibu Studia, di mana Mida adalah suami dari Chantal Kreviazuk, dan sisanya direkam di dekatnya. Dalam situs web resminya, Avril menerangkan bahwa dia telah belajar banyak dalam proses rekaman sejak album pertamanya Let Go, "I was involved in every aspect of making this record. I'm very hands-on. I knew how I wanted the drums, the guitar tones, and the structures to be. I understand the whole process so much better this time because I've been through it. I'm really picky with my sound." katanya.
