I think it's a combo of both, fanbase and hit single, it's a timing thing. Fanbase is more important, because this dude is touring and selling out decent size events for a nigga with one official single, it's a matter of releasing that single he has with Trey Songz now and grabbing that mainstream audience. This whole idea that a big single is the end all be all is fucking false, look at niggas like Gucci, Wacka,etc all over the radio and bricking when their albums get released and look at niggas like Kid Cudi with no video and no massive singles putting up numbers.
Fanbase > Chart position imo
