With largely positive reviews and the benefit of months and months of pre-release hype, HITS is predicting that Lil Wayne’s Tha Carter III is “on track to be the biggest debut of the year by far.” That being said, the debuts this year haven’t been all that impressive, with Mariah still reigning at the top after 463,000 first-week sales. Of course, even if Weezy pulls off a half million plus between now and Sunday, Coldplay is likely to destroy his numbers the following week. All of this news is making Usher very, very sad right now.
