Name of this Hip Hop song

-It's a relatively slow song that might be classified as hip hop
-sung by a male with another male rapping in the middle of the song
-has a female sing at some parts
-has a pretty instrumental/beat
-sounds like a piano (maybe?) during intro and chorus; sounds like only two notes going doodoo doodoo doodoo
-Sounds like the hook says "the bottom line" or "I don't mind" or something that rhymes with that
I think it's new (meaning within the past couple years)
-I think the male and female singer both sing the hook

Please help! It's driving me nuts!

Do you know any more of the lyrics? If you do can you type them up...

I don't and I don't even know the lyrics; all I know is that the hook sounds like they say "I don't mind, I don't mind" or something that rhymes with that like "It's the bottom line, bottom line".
