50 Cent Curtis (2007)
Curtis never stood a chance at being judged fairly. It was released alongside and in competition with what is arguably Kanye West's best album, Graduation. Plus, aside from "I Get Money," all of its singles stalled. But that doesn't mean they weren't good. "I'll Still Kill" harkened back to 50's hardcore content, but added Akon for an actually enjoyable pop sheen. The Justin Timberlake-assisted "Ayo Technology" was an electronic banger, but 'Ye's approach to the style ("Stronger") connected better at the time.
Beyond singles, album cuts like "Man Down" and "Movin' On Up" were fire, and came the closest to 50's former, more celebrated styles. Curtis wasn't perfect, but it had high points that were unfortunately overlooked.
