Heard it on the radio =_=

i heard this song on the radio, and have spent (literally) HOURS looking for it.
It's hard to understand the lyrics in this song when its playing (at least for me)
I know that it's sung by a girl named Alexis or something, and Jay-Z (or some guy that said J ????. But it sounded like Z,B,D,E,G, etc.

All I know:

Let me introduce you to a young lady (pause)
Sixteen, ready for her/my big break.
(something, something something something something)
Never thought I would make it

Chorus:
It don't, matter what people say.
Gonna, make it anyway.
Won't stop,
(something, something) to the top,
you can choose to love or hate meh! (x2)
