Wale is actually making really good use of this time between when his album was supposed to drop and the day it was delayed to. He is dropping a bunch of new tracks that are pretty good leading up to the release of his album. All of these tracks are not going to be on the album, so we will still have plenty to hear when it drops early next month. I am surprised this one did not make the cut since Pharrell is featured on it, but hopefully one of the other songs Wale made with The Neptunes will make the cut.
EDIT: Never mind, Wale has confirmed this will be on the album and he has leaked it on his own.
