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

I feel that any person is free to listen to the music the music they want at their own free will. However, their choice to do so is sometimes heavily influenced by the record companies and how they over-publicise their artists, e.g. radio play and television. Theorist, Adorno, agrees with the statement that the music industry looks at success with certain bands and produces similar sounds such as boybands like Westlife and Boyzone, I, too, agree with this as there are phases in the music industry when a certain type of music is predominantly popular. The control of the music industry has been reversed and now us (the consumers) are more in control. With the advancements in technology, it has now been made easier for consumers to have whatever choice they want in music. With websites such as iTunes and illegal downloading, people are free to buy whatever they want.
