The song "Sorry," which is a defiant breakup song and included Serena Williams in the video, is the latest in a legacy of tracks by that name. Last year, Justin Bieber rounded out his apology press tour and cemented his comeback with the chart-topping track "Sorry." And before the Biebs, there was Madonna with the single "Sorry" off 2005's Confessions on a Dance Floor, as well as many other artists with songs by the same name.
