lol, just because you're a fan of someone doesn't mean you're obligated to like every single thing that they put out. i'm sure vanessa appreciates people telling her their real opinion on her material rather than the glazed over "omg i love it" opinions.
i personally like the song a lot, but i'm well aware there are others that don't and that's fine. it's their opinion. i'm sure they wont stop supporting vanessa.
oh, and i really don't think vanessa and irv are dating. they just have a really really strong friendship aswell as a business relationship.
