I know Dice can't SANG, not like Bilal or maybe like Jill Scott or someone who's a classically trained singer, but i think the texture and the struggle of him getting through the words kinda embody the spirit and state of mind of Redford. like he wouldn't be someone with a polished sensibility because of his environment and the voice of Dice kind of matches.

of course this doesn't account for Bilal singing on The OtherSide, but every explanation can't be precise all of the time. ;)
