I think the problem with Invisible is the week it was free on iTunes for a week. It was downloaded a lot, close to 500k iirc. Everyone who liked the song then, downloaded it for free. Kinda sucks. But still, she's a new artist with a solo song so I didn't expect it would hit top10 or w/e.
MLJ's succes is amazing
I expected it to be a minor to mid hit, but it's slaying worldwide!
