Busta Rhymes and J Dilla

Boogie was undoubtedly king of the mixtape in '07, but his latest may be his best yet. With a gold mine of original material — demos and outtakes produced by J Dilla and supplied by Busta from his personal vaults — Boogie has created one of the most focused and rewarding mixtapes ever. There are lots of reasons to love it — including Busta's growls in the hilarious "Takin' What's Mine" as well as "Best That Ever Did It," a superb pairing with Rah Digga. The beats — whether sample-sourced or created from scratch — are consistently tough and serve as another sad reminder of Dilla's untimely death from lupus in 2006 at age 32. The only downside: The free download will probably inspire momentary feelings of guilt — as in, Shouldn't I have to pay for something this great?
