A month ago, Wale and his team released the "Bad Rihmix," and the following week, the song outpeaked its original peak (#25) and landed at #21, thanks to the Rihmix. Currently, the song is top 30 combined on iTunes (and has remained nearly steady there since the release of the remix), and it is slowly gaining at pop radio while losing steam on its parent formats (Urban and Rhythmic).
Does it have a chance to crack the top 20, or is it completely done and will fall down the charts?
No. It won't do much on Pop radio and it's dead everywhere else (lost 2 million overall today.) And it isn't a big streaming hit either. Maybe if they release a video for the remix, which I doubt will happen.
