What a Girl Wants by Christina Aguilera is featured in Mash-Up, the eighth episode of Season One. It is sung by Rachel. She is accompanied by Puck, who plays the guitar.
The two of them are coming up with mash-up ideas together at Rachel's house. Puck stops Rachel during the song and they end up having a make out session. Rachel only sings a few seconds of the songs rather than the full version.
The song was unreleased.

Rachel:
What a girl wants
What a girl needs
Whatever makes me happy sets you free
And I'm thanking you for knowing exactly
What a girl wants
What a girl needs
Whatever keeps me in your arms
And I'm thanking you for giving it to me.
