r&b music fans..what are some good duets that are not well known because they werent released as singles?

It can be either boy n girl, both girls, or both boys....I can only think of one example right now which is the 'Alone' song by Mary J Blige ft. Dave Young

Thanks in advance

Trey Songz, Chris Brown, & The Game - Wait.

It was on his recent mixtape Murder He Wrote 3.

It's not really R&B though, that's what I like about Trey, he has so many different styles.
