Just by how the biggest names in hip hop are releasing albums. Not saying Wayne is still a good rapper but IANAHBII in feb, possibly Tha Carter V, Ems album, probably one from Ye, possibly one from Jay, a Drake album, 50's album, probably a SH and Yella album, and a Pusha album. And that's just a few. Will 2013 be the biggest year hip hop has seen, just in terms of sales, in at least a decade?
Edit: how'd I forget about tech as well
