IMO, none of the contemporized versions aside from the lead single are strong/radio enough as a strong single contender. That being said:
the studio version of DYKWYCA - the one that leaked in 2010 - would have been a smash. That version IS THE ABSOLUTE BANANAS and I would spend my days requesting on the radio. It still makes me giddy when I it comes on my playlist. No question. I remember my face melting when it came out.
Blue Gangsta original - I have at least three or four versions of this song, and that hook is soo damn catchy. And the songwriting alone is already contemporary enough to catch on to today's audience, but yet retro enough for everyone to know where it came from.
Original Xscape would also be the best idea, IMO...they should just let HIS original music speak for itself.
God I wish I could get my external drive to work, I've been dying to listen to these tracks!
