“My daughter’s heaven sent/She rock Gucci, Louis,” Chief Keef raps. “Got Them Bands,” a bonus track, is the most direct. Surprisingly, “Finally Rich” is an album that at least doesn’t ignore fatherhood. It is also, thanks to Young Chop, who produced about half of it, exuberant and pugnacious, a stress reliever of an album. Like the mixtapes that preceded, it’s relentlessly dark and sometimes lifeless, at least in the lyrics.

There’s plenty that’s troubling, and troubled, too about his major-label debut album, “Finally Rich” (Glory Boyz/Interscope), which was released this week. Chief Keef is 17, and appears happy for the most part to be seen as a problem child. The same one whose music is in part a catalog of gang-related boasts and threats. The same person who spent a significant portion of 2012 under house arrest in connection with gun charges. This is the same Chief Keef who had another of his Instagram accounts suspended in September for posting a photo of himself receiving oral sex.

Exactly one rap star has an Instagram account wholly devoted to affectionate, intimate, cute pictures of his child: Chief Keef.
