Currently, on iTunes, Fleetwood Mac’s 34-year-old album Rumours is outselling Jennifer Lopez’s just-released LP Love?, following this week’s Mac-heavy Glee episode. Perhaps J.Lo chose the wrong Fox series to sign up with? Despite the fact that her single “On The Floor” is a certified smash after having sold roughly 1.6 million downloads (it’s #7 on this week’s Hot 100 chart, after previously peaking at #5), Billboard predicts that first-week sales of Love? are going to have the singer moving about 60,000 copies, with new albums from Beastie Boys and Fleet Foxes — not to mention the latest NOW compilation and Adele’s two-and-a-half-month-old 21 — coming in ahead of her. Time to mobilize (and cough up some cash), J.Lo fans!
