On his second album, actor-turned-rapper Childish Gambino wields his nerdiness with newfound confidence, spitting meditations on Internet culture with fluency and ease. The Community star (a.k.a. Donald Glover) drops winking bars like “Never gonna reach a million/Eventually, all my followers realize they don’t need a leader,” while the click-worthy upstarts Chance the Rapper, Kilo Kish and Jhené Aiko make cameos. The production is full of twists and turns – jazz fills, dubby static, R&B singalongs – that evoke scrolling endlessly through a Tumblr dashboard. As a concept album on man’s most abstract concept, Because the Internet is more than worth the download.
