Ludacris has thrived in his singles by reveling in his debauchery, but that's not his only mode. He gets lyrically introspective on “War With God” and “Growing Pains” and proves his punchline wizardry on tracks like the DJ Premier-produced “Mvp,” which stacks rhymes on top of rhymes. And competition definitely ups his game; he shines when sparring with his peers, like going bar-for-bar with Lil Wayne on “Last of a Dying Breed.”
