I dunno about this. The «la la la la» bit is nice and all—great even, but the rock drums aren’t up my alley, Jay-Z’s voice is TIRED, and you can’t dance to it, which is a huge minus. Its wiki page claims both Mary J. Blige and Akon passed it on, and somehow the song actually smells of having been mangled, focus-grouped, and whatnot. I don’t know why; it’s just an odd feeling I get. I like that she so daringly tries on new genres all the time. (Actually, the first thing that struck me upon viewing the video was that my beloved Rihanna had lost all of her nymphetic allure, boohoo, but that’s the inexorable hands of time for ya.)
