Prince has made 3 mistakes with this release:
1) 2 original discs is creative overindulgence and way too much music to be consumed at one time. Albums are dead, and long 2 disc sets promise that this release will be forgotten in no time. Prince would've been a lot better served by releasing just a few of the very best songs rather than diluting whatever good material he has with the filler that we know will be there.2) the third disc by his unknown protege might get her some short-term exposure, but it's no guarantee of anything beyond the lifetime of a very short candle. It's already competing with Prince's two other discs, which is competing with all the other new releases, which are competing with Prince's catalog, which is competing with the internet, games, social networking, television, and all the other things that take one's attention these days.3) choosing Target as the exclusive distributor probably wasn't the smartest business decision that Prince could make. Wal-Mart and Best Buy have longer reach and more traffic. Unless, of course, it was the only deal on the table.
It'll be interesting to see just how well the release will do, but the prediction here is it'll tank.
