R&B Song sung by female
I'm looking for the name of an r&b song that I can't remember the name of.
It's early noughties and has a female singer, the hook is five notes of what sounds like a flute. The notes of the hook are D,A,B,G,E. The first and last notes are held longer than the middle notes.
Unfortunately these are all the details I have, it was popular back when it came out and I still occasionally hear it in clubs.
Any help would be much appreciated, thanks.
EDIT: I found it after a bit of scouring the Billboard charts.
It was Me & U by Cassie
