Help with a song

[ucilatin]

I was at a club last night here in Los Angeles and I heard this freestyle song, I have heard it before but I dont know the name of it. I think its a guy singing it, lyrics go something a bit like
Cant wait for tonight
Cant wait all night...
I know its vague but thats what the chorus starts off at. It starts with cant wait for tonight...then it goes into cant wait all night...Any suggestions...?:cool
