After 24 weeks on the charts, Lil’ Wayne’s Carter III has sold a whopping 2.7 million copies domestically. While the label executives at Universal Motown and Wayne’s bank account are the obvious winners here, a few up-and-coming artists have also benefited. Signed to Wayne’s Young Money Entertainment, rapper Mack Maine was able to snatch a guest verse on the remix to Got Money; heading into ’09, he seems poised to be the next artist on the label to drop an album. Before he does, however, Maine will unleash a collaborative project with Don Cannon, entitled This Is Just A Mixtape, which will include the Kane Beatz-produced cut Throw It Back. Though the track isn’t Wayne’s best feature work, it demonstrates the impact that he will continue to make through his ever-expanding roster of artists.
