And so 50 brings the agony with aplomb: "I don't smile a lot/'Cause ain't nothin' pretty/Got a Purple Heart for war/And I ain't never left the city," he spits on "If I Can't," a cocky cut that mates 50's deep, cottonmouth delivery with a bare-knuckle beat. Elsewhere, there are plenty more reasons why this disc smashed Snoop Dogg's record for first-week sales by a rap debut: Dr. Dre's spectral keys turn the Ja Rule-bashing "Back Down" into a hot-headed highlight; "Like My Style" is a combustible blend of gin and gunpowder; album-closer "Gotta Make It to Heaven" is Mean Streets set to wax, making it a fittingly violent climax to a disc as indelible as scar tissue.
