Following hot on the heels of the Dove commercial showing the before-and-after of a model (through make-up, Photoshop touch ups, etc), some people have exposed some of the techniques used to create and market a pop star.
You don’t need musical talents to pen songs – someone can take care of that. Can’t sing, or tone deaf? Sound engineers will fix that. Just someone (probably armed with market research on what the market wants, and loads of cash) who’s willing to make you a star, and you are on your way. Packaged, artificial and hollow.
