I think the other reviewers are getting their wires crossed. This is what's known as a "Mixtape" and is not the long-awaited follow up to D'Angelo's 2000 classic "Voodoo".
This CD is a mixture of previously released obscurities (live b-sides, contributions to sound tracks)and a couple of "new" tracks in Really Love and Go Back 2 That Thing - a meandering guitar led mellow Sly Stone influenced semi-ballad and a meandering keyboard led Sly Stone (again!) influenced instrumental jam respectively.
So basically Y.O.D.A. is a semi-official bootleg with all the variable sound quality, minimal information and packaging and thrown together nature you'd expect.
All the same, speaking as a big fan of D'Angelo's work who is hungry to hear some more stuff from the great man, to be able to hear 79 minutes of "new" (at least for me), mostly quality material is far far better than nothing (which is pretty much what we've got from the great man over the last 5 years or so).
Should also mention that the opening track, Features, appears to be a cut up of various disparate works in progress some of which are really, really excellently funky, flowing and mellow just as you'd want them to be - can't wait to hear the finished album cos from the sound of it, D'Angelo has been sitting on some decent material!
Peace'n'out,
