He hasn't done a cool outro like that since CD it ruins the song but it's much appreciated. Get the soundcloud version before it gets taken down.As far as 30 hours goes:
Andre 3000 helping with the outro is nice.
Kanye getting a call is hilarious.
But Ye giving SOs and taking a call at the end kinda hurts the amazing ride out of the track
Vlado did it. Of course it's a messAs I feared, a hack ass mastering job.
