The thing is none of 50's singles have been really catching on, and they're getting pretty desperate about it - see the recent Robin Thicke debacle (and, yes, I really doubt 50's been throwing around TVs at label execs). Basically, they've been spurting out songs frenetically for months now hoping someone would just notice. And suburban white boys have been ridiculously - aggressively? - out of the loop for almost two years: they're simply not buying hip-hop like they used to (last year was the worst year sales-wise since the early 90s, I think). Not to mention the general awfulness of his last album (as opposed to his second, which was only, uh, halfway awful). I mean, if hip-hop's goldenboy, TI, hasn't managed to reach platinum one month in, who's seriously betting on Curtis Jackson? (I'm so not gonna make a vitamin water joke, by the way.)
The Massacre outsold Late Registration by about 8 million records. That was 2 years ago.
Still, I'd rather methodically review 50's entire output than buy a Kanye West record. And that's not - uh, solely - because I'm cheap.
