She didn't become a Musicart 
because she wanted to.
لم تصبح ميوزيكارت بمحض إرادتها

porque quisiera.
No se convirtió en Musiccato
porque quisiera.
Elle n’a pas choisi
de devenir une Musicart.
Non è diventata una Musicart perché lo voleva.
Ela não se tornou uma
Musicart porque quis.
Она стала Мьюзикартом
не по своему желанию.
