What songs for me to sing?

I sing pretty low. I'm a girl, 14 and I cannot sing high pitched notes. Mariah Carey, no way. I can sing Lady Marmalade by Christina Aguilera, Pink, Mya, Lil Kim, and Missy Elliot. Just not the high parts so much. I Believe I Can Fly is a song I excel in from what my language arts teacher and class said. So, can you tell me some songs for me to sing?
