Are the audience for popular music created by the music industry?

The common Marxist view held by people such as Theordore Adorno is that popular music is simply a commodity and is standardised. Some say that popular music has become homogenised as big record companies make music that they know will be successful as there is a lot at stake and they don’t want to take a risk therefore copying what is already out there. On the other hand there is still a wide variety of music being created today and it can be argued that this homogenisation has created  a higher level of diversity . Certain bands like Radiohead can get away with giving their music away and charging their fans as much as the fans think it is worth as they are already well established and are making a very good living from music but newer bands need recording companies to get their sound to the public and make a living.
