What's that song???

[surfershure]

Hey, everyone. :] I'm new to all this, so please forgive me if I do anything wrong. =X... anyway, my friend burned me a cd with this particular song on it about... 4 or 5 years ago. I've never really thought about what the title or who the singers were until now. It's difficult, but I would definitely appreciate if anyone could help me figure this out. Well, there's this rapper in it that raps in English and this female singer who sings in mandarin. Uhh... if it's any help... I can give you a bit of the lyrics from the rapping:

when i hear your voice over the line

all i wanna do is keep you on my mind

... (some parts i don't know)...

What you tell me baby boo

what you want what you need maybe

i'll be the one that you need till i doubt baby

let me tell you all the things that you don't realize

I'm sorry, it's pretty vague, but I hope someone will know :] thanks a bunchies!

That's "等不及" by Yuki (徐懷鈺) and Yoo Seung Jun (sp?).

Edit: If you can't read the Chinese, the song is "deng3 bu ji2" (Can't wait) by Yuki Hsu and Yoo Seung Jun. I've done that song karaoke before.
