What is Christina Aguilera feeling emancipated from? you may ask, digging into “Liberation,” her first album in close to six years. One track offers some tantalizing clues. “I ain’t built for no fake shit,” she wails, almost gutturally, over rock guitars and faux crowd noise produced by Anderson .Paak. “It’s good pay,” she additionally points out, but “I can’t move with these chains on me / I had to get free. … This ain’t a game to me.” The song title: “Sick of Sittin’.” Now, if it were any other star expressing an animus toward chairs, we might think she was speaking figuratively. But it doesn’t take much reading between the lines to divine that this openly disenchanted ex-“Voice” jurist really has written one of the few breakup songs ever to celebrate splitting up with a TV show.

There are other titular connotations along the way.
