Following the release of Let Go, Lavigne worked with new collaborators for Under My Skin, including guitarist Evan Taubenfeld and singer Chantal Kreviazuk.

Lavigne continued to work with Magness, although only "I Always Get What I Want" would appear on the reissued album in the form of a bonus track.

[3] The lyrics of "I Always Get What I Want" carry a message of entitlement, with Lavigne dedicating the song to "any young girl out there who always gets what she wants".

Annabel Leathes of BBC Music compared the song to English alternative rock band Transvision Vamp, declaring that "'I Always Get What I Want' delivers a healthy slap in the face of authority ... and suggests that Avril isn't quite ready to grow up.
