's fourth album in eight years -- his fourth consecutive release to feature his first name in the title -- is his most modest and low-key set. Some listeners might bemoan the increasingly reserved nature of 's releases since the singer's unexpected 2000s resurgence, but the direction is natural. It would make little sense for him to continue teaming with songwriters and producers accustomed to working with pop-oriented R&B artists less than half his age.

While it does not feature as many standouts as the three previous "Charlie" albums, is another enjoyable and genuine addition to the catalog of a funk heavyweight. ~ Andy Kellman
