Agreed, and that's what's bugging me: I missed a bit in the article the following: how do they get massive groups of people buying into the products they are selling, every time? If you look at the whole pipeline, from writing the 'hit' to recording / mixing / mastering to getting it on iTunes (record store?) and the shows live in the halls / stadiums, where and more importantly: how, are they getting the people that far that they part with their money to 'own' a copy of these, often dreadful (music wise), songs?
It is, IMHO, that part of the whole pipeline that they have mastered, not the song writing/recording: the product isn't the music, the product is something else, the front person ('artist') + the whole entourage around it, but it's fascinating how they manage to construct _that_ entourage that is sought after by people with money to burn. they must know an answer (which is sold in the form of the artist+entourage+shows+music) to an unknown question / benefit sought a lot of people have.
