Absolutely true, sir Cel. Look at Tatu- once they did a couple of English- pop/dance/whatever songs, they got some airtime and a brief exposure in the States, even a little appearance at the MTV music awards. Ewa could only hope for as much success, at least stateside, but with her all-natural beauty and body, a little english-versions of half-decent club/house songs would go a long way. Her songs are too plain of what I've heard to demonstrate any real talent; she could be another pro tools-finessed beautiful stand-in for a behind-the-scenes writer. If she really wants to be a musician, she needs to find an authentic voice, both in terms of what kind of music she sings, and in showcasing more of her voice than short little riffs.
God knows a lot of people would just get gobsmacked by her gorgeousness, and of course clueless maroons would think she had implants! But that can still translate into real record sales, if she can get some songs that are more catchy, more "true" to herself and not just cookie-cutter tunes, and are sung in English. MTV and the like need never touch her for her to develop a healthy career as vocalist/DJ touring around Europe.
She'd never really make it big long term though, I think, because people would overfocus on her breasts and not take her seriously unless she had the pipes of a Mariah Carey or Christina Aguilera- and I don't think that's the case. Dolly Parton is the only one I've seen surpass her caricatured looks and a long, vibrant career, and that was because Dolly is immensely talented and devoted to her craft of authentic country and bluegrass music. Ewa would have to tape those utterly stunning breasts down or a lot of people would never take her seriously, even if she was very gifted.
