I know nothing about music to that degree I can more just tell if someone can sing or knows how to lay on the auto tune so you're probably right!I think she sounds good in her songs, but then again, her songs are not in the least vocally demanding. What I mean is she probably has ear for music, she does sing clear, but her vocal range is not very impressive.
Also comparing her to Cara I had in mind that they are both fat and their daddies bought them careers - although I'm not sure when it comes to the latter but it's a frequent rumour I've been hearing since she started being big (pun intended).
As for buying careers you're definitely right on that aspect too I've heard its true of both of them and it wouldn't surprise me in either case. I just have a strange liking towards Lana and think she'd look good if she lost the weight whereas at this point I would hate Cara even if she was a twig
