There was something Shakira was planning to do today, but it just isn't coming to mind... Oh, right: the international pop star was going to not think about a certain man. If you haven't guessed from the title of album lead single Can't Remember to Forget You, carrying out that plan proves mighty difficult. Here, producer John Hill's reggae-infused boardwork bumps in the background as Shakira laments her inability to stop reliving rose-colored memories of an ex who did her wrong. Rihanna assists on the guest tip, sympathizing with her collaborator's plight in a middle verse many will doubtless interpret as autobiographical. If you're having as much trouble getting this song out of your head as Shakira is getting that guy out of hers, you'll want to watch our pages for further details on her next album. The artist's fourth English-language LP, the project currently awaits a title and release date.
