New Music: N.E.R.D. and Lil' Wayne Feat. Jay-Z

Tomorrow is a big day in music - with the release of N.E.R.D. 's Seeing Sounds and the highly anticipated, Carter III, both dropping. So just in time for new music Tuesday I'm giving you two tracks you're sure to rock to. First up is a bonus joint off of the Japan release of Seeing Sounds, called Lazer Gun and second is that bangin' new Lil Wayne feat. Jay-Z, Mr. Carter.
