Brawny - Global Superstar?

At work, I use Spotify to listen to music in the office, and this works well. Yes, it interrupts every so often with adverts, but usually these are short and inoffensive...

I say usually...

There is one advert that keeps playing, advertising Pixie Lott (which, incidentally, is a stupid name). Fine, not really my bag, sounds generic and dull to me, but whatever.

But there's a phrase that's used in the advert which keeps annoying me...

"The UK's newest global superstar"

What?

So, basically, she's a global superstar is she? Well off I go to check the facts about her sales figures (because I'm at work, and you know, it's either do that or ACTUALLY do some work).

Her first single (the imaginatively titled "Mama Do (Uh Oh Uh Oh)", which frankly is a title so rubbish you wonder if they took a book, shredded it, threw all the bits in the bin, and then pulled out two words, before adding some random grunting noises after it, but I digress) does appear to have been released in quite a few countries, so she has definitely had an attempt at the global market.... however, it only made top 5 in this country (1) and in the Eurochart (5). Her second single (the title of which is marginally better than the first, although still horrificly generic - "Boys and Girls". Seriously people, work harder on your lyrics/titles!) has charted in three territories, the UK (1), Ireland (4), and again, the Eurochart (10). Her album has been released in six countries, with chart positions ranging from 6 in the UK to 92 in the Netherlands...

Now, unless I misunderstand the term "Global Superstar", then she is not one. I appreciate she may become one (I hope not, because she is generic and bland, but that's never stopped anyone before..) but she isn't one now. So surely they can't say that she is? Let's just check the definitions of the words..

Global - Now I assume that this refers to the first definition "Pertaining to the whole world; worldwide; universal" and that they are not calling her globe-shaped. Which she's not. I mean look at her. She has an annoying looking face, certainly, but she doesn't look like a globe. So I assume they are utilising that initial definition of global. (Being as the other definitions of global make no sense within this context, I mean, she's definitely not a piece of software..)

Superstar- OK, both of these definitions basically say the same thing - that you are very prominent or successful. Which she isn't!!

I know it's advertising, and the fact that they bend the truth should be less surprising than a male stand-up comedian telling a joke about the fact that women take ages to get ready to go out, but it still amazes me. I'm sure there are much better phrases that they could have used. Like the following examples:

Pixie Lott - The UK Chart topper
Pixie Lott - A shining example of the lack of taste in the UK Music buying public
Pixie Lott - Yet another blond singer-songwriter
Pixie Lott - Gives generic a distinctly average name
Pixie Lott - It could be worse, at least I'm not an X-Factor winner

Any other suggestions?
