I heard this song near the end of October 2008 and it's been driving me INSANE because I can't figure out or find out what song it is! I'm sorry there isn't much to work with, I'm able to hum what the tune sounds like but that's about it.

It is a female vocalist and the track is a little funky.

I believe the end of the chorus goes something like this:
...and I'll give my love to you (or)
...and I'll give my heart to you (or)
...and I'll give it all to you

The "to you" at the end has her voice higher pitched on "to" and lower when she says "you".

I wish I could offer more to help find it but as it stands I am pretty much in the dark. Thank you in advance for your help!
