LOL this is funny. I think it's the paper trying to make something out of nothing. I've heard Nessa jokingly say how she has more than one song on numerous occasions. We all know she doesn't do it out of ego, it's just that she's only known for ATM and that's how she tells people for the billionth time that that song doesn't define her.
And I think Vanessa naturally has a slight cackle to her laugh. It's more of a giggle though. It's cute.
