Stuck in my Head!

This has been going through my head non-stop... maybe you could guess where it came from?

I don't wanna wait
I don't wanna wait
I don't wanna wait
I don't wanna wait
I don't wanna wait for you

Cause I need you
Can't you see that I need you?
Cause I need you (I need you)
Can't you see that I need you? (I need you)

Baby it's you I want,
So stop wasting my time
And baby it's you I need,
So please make up your mind
It's time to choose

-yikes-
