Jennifer Lopez’s latest single — the international smash “On the Floor” — opens with this line: “It’s a new generation of party people.” And luckily the singer has taken note. Lopez, 41, isn’t the same star she was 10 years ago, when she dominated both pop and urban music charts. She struggled with 2005’s “Rebirth,” and was worse off with “Brave,” which came two years later.

Lopez has never been a musical icon, and she probably never will be. But she is a great entertainer — and that’s reflected throughout most of her seventh album, “Love?”
