Lil Wayne, ‘Dedication 4′ – Best Mixtapes of 2012

In September 2012, Lil Wayne released the fourth part of his 'Dedication' mixtape series. On the Gangsta Grillz project headed by DJ Drama, Weezy takes on 15 instrumentals from some of 2012's most popular tracks including Rick Ross' 'So Sophisticated,' Future's 'Same Damn Time' and G.O.O.D Music's 'Mercy.'

Wayne brags about his library of lyrics rapping, "I got bars n----, and it's happy hour" on his version of 'Cashin' Out.' The mixtape, his 18th one, continues on with many of his playful analogies.

The project was the first since his last album, 'The Carter IV,' in August 2011. Before readying the release of his 10th studio album, 'I Am Not A Human Being II,' this year, Weezy owed hip-hop something new and delivered 'Dedication' to the masses.
