It's called "Sound of Love" and Cassie didn't try to recreate anything. That's not even her single but DJ Komori's and it was only released in Japan last year.
So, I love this song. I love that it sounds nothing like what's on the radio but still fits in. It's a smart song. Nicki's verses are great, and Cassie surpassingly is to (I guess it was her song first). I like it's laid-back sound as well.
