KILL IT WITH FIRE. That was my first thought when this surely-inevitable turd remix of will.i.am’s, “Scream & Shout,” featuring Britney Spears, Hit Boy, Waka Flocka Flame, Lil Wayne and Diddy plopped into my email shitter. Could you think of a more cynically calculated move to shoe-horn in as many names as possible into one song in order to ensure maximum market coverage? But wait a minute, Britney might single-handedly save this mess. Scrape the rest of the phoned-in verse barnacles off the bottom of this thing’s hull (and even those are starting to wear me down after a few more lessons) and what you’re left with is Brit Brit on her mature-phase Madonna spoken-word shtick. It’s kind of amazing.
