I would have to say that it is a combination of all of those things. The music industry is focused on what sells. For some reason the masses are suckers for really shitty, talentless, music without substance. If you even want to call it music that is. It seems that they target very young teenagers that are very impressionable...between the ages of 12-15, because they know those kids are going to listen to anything.. if the airwaves suggest that its cool to like it or television advertises it as so...it isn't about putting good music out there anymore...it's about making money and not the quality of the music. So basically the cycle goes like this...radio plays shitty music, younger kids are told its cool to like shit music, they listen to it to fit in, those kids that are musically inclined immitate the shitty music they are told is cool on the radio, which exposes the shitty music to other people, and it spreads like a wild fire, until its all over the place, so the record industry makes their money, the promoters promote the shitty music that the record industry puts out, and the kids play this shitty music out at the clubs. the cycle repeats...and its going to keep going that way...until the people at the top are removed and replaced by people that give a damn about good music.
