Again, until you know the person's biography, do you really know how talented they are? I don't much follow pop music, but there have to be talented pop stars as well. Insanely so, even. Look at Madonna, for example. No one does that well, for that long, without having a lot of talent.
The simple dismissal that all pop stars are created by the industry is the same as dismissing Criss Angel because he's a product of his marketing. At some point, those people had to do something to get noticed. They had to have some talent, some trait that brings them above the rest of the masses that are trying to become stars.
