“Throughout my life, I always felt like I got a second chance at everything somehow,” Big Sean told Trevor Noah on The Daily Show late last month. Second chances and the process of reinvention have always marked the Detroit rapper’s career. Long gone are the days of strip club anthems set to MC Hammer samples; two years ago, Sean took a plunge into the moody, inky Dark Sky Paradise, his most ambitious project to date, while I Decided offers the most sonic diversity of his career. But as admirable as Big Sean’s penchant for rediscovery is, it’s only extended as far as the instrumental spaces he inhabits. I Decided still suffers from the same problem that every other Big Sean album does: Big Sean himself.
