Much of Empire’s success so far has been because of its music (thanks, Timbaland!). And that’ll continue tonight, when Courtney Love joins the cast as a washed-up star from the label’s glory days. Natch, for her grand introduction, she covers Al Green’s “Take Me to the River” (though it was apparently supposed to be Patti LaBelle’s “Messin’ With My Mind” — can you imagine?), and it’s not half the disaster you’d expect. Seriously.
