This first joint, “Can’t Wait To Hate U” is a reference song for Mariah Carey which is supposed to be on her upcoming album, *Memoirs Of An Imperfect Angel*. This is her 12th full length album; DAMN!
The second joint is The-Dream basically covering Jamie Foxx’s cut “Rainman” which was on his last album, *Intuition*.
Now that I think about it, this “Rainman” cover may be old. The-Dream probably wrote that song for Jamie (as he did a few others on that album) and recorded this a while back; but it’s just surfacing now.
