92. Lil Wayne "Help" (2007)
Album: The Drought Is Over 2 (The Carter 3 Sessions)
Though Wayne had previously spit the same verse on Da Drought 3's "Live From The 504/Shoulder Lean" freestyle, "Help" contextualizes his Beatles punchlines with an obvious but endearing (and obviously unclearable) sample from the Fab Four themselves. Meanwhile Wayne engages time itself in a rap battle-"I gets hotter by the tock while I sizzle to death/I just tell the clock 'give me a sec"-and perfectly sums up his Carter III era rap style in just one line: "Every time I hit the track I'm like an energy pack."
