I have to say I came to this song without any great hope that I would like it. Although rap has become a vibrant and wildly popular musical form, rap songs rarely make good pop music. This is a fantastic exception and I hope it delivers Lil Wayne's second US no 1 (after Lollipop) for his own account after collaborating so successfully with the likes of Eminem and Jay Sean.
This is actually more of a rock song with a lot of guitar (including a great intro) and Wayne's raucous, heavily auto-tune distorted vocal is the sort of thing you hear on Scuzz.
This song also has someone else involved - it features "Bedrock" rapper Nicki Minaj, who adds a sweet and melodious hook and a glorious expletive filled outburst in the middle.
My favorite part is the end where Wayne delivers the sort of finish that fills rock stadiums. I actually hated Lollipop so this cracking song was a welcome surprise.
