Yes, I see what you are saying and there is this "X Factor" effect. Agreed.
People do still have to consume this rubbish though. As we always say in the motor industry - you can try to bend consumer opinion and lean them towards a product or even a style of product. Ultimately, there is no point in making stuff that people don't buy and no manufacturer has that power to make the consumer lean that way. They can persuade. But persuading and commitment are different things. The consumer has to commit and that commitment is a strong driver as to whether something flies or not.
Sometimes (I know not so often) the big marketing machine does fall over when people have said "Enough!"
In the music business, which is vastly more fickle than may other businesses, through life of more modern style (1950s on), there has been a rebellion of what has gone before. That's the reason why the different genres were set up. Probably the most significant rebellion was the Punk era that rebelled against the pomp and technically mind boggling rock acts that had gone before. Ultimately, it seems weird now that there were these rifts, when you see artists of 2 opposing genres of the past sit in the same show or whatever, when 30 or 40 years ago, they would strangle each other.
But consumers also got fed up with a what was current.
Back in the day, when there were these changeovers, there were 3 points that I recall as being dry years, bereft of imagination but more importantly (as there have been dry years before and lots after), forming the boring middle of a very interesting sandwich. 1971 / 1976 / 1983.
'71 because the Beatles had gone for good, Glam Rock had not really taken a hold yet, the Stones / Who / Kinks were becoming a bit old hat. The heavy rock acts, like Led, Purple & Sabbath started just pouring into the big live stuff, especially in the US and could be acts regarded as starting all the pomp that followed down the heavy and prog rock lines (the untouchable) and thought they were too good to produce singles (although I know that Deep Purple had some). But it was a bit of a void as we had Dawn telling us to Tie a Yellow Ribbon and The Searchers teaching the world to sing. I mean, this was pretty dry and uninspiring stuff that was popular. It lasted until T-Rex and Bowie sorted it all out for then for the doors to open down that path.
By '76, Glam Rock had finished, Punk was yet to get going and then we had Brotherhood of Man heading our charts and Sailor and all that dross. OK, through time, there has always been dross (sorry if people like that stuff - I find it all a bit uninspiring, that's all). They reckon that both 71 / 76 were dry years because there was too much of what you would call non earth shattering music. I mean, even the Stones themselves said they were washed up by 76 with Fool to Cry. OK, it could be regarded as a classic today but, IMHO, was a world away from Paint it Black and Pale Shelter. Shame that Ronnie Wood had just left the Faces to go into that group the year before to find he was now in a band that was washed up.
1983 is interesting year because again, there was nothing to hang your hat on. Pail Young did try to hang his hat on something but missed IMHO. Durans/Spandau, whilst still reasonably good, had lost their New Romantic hard edge and we bathed in the summer of 83 to Red Red Wine of UB40. I mean, it was all a bit bland. Then The Smiths came along and set a new genre off that really came to a crescendo through the Stone Roses into Oasis and Blur.
So there have been dry spots in time before and I can't go on through them all as the posts would not only be long, but also wildly off topic as it is. But there has been this void for over a decade now where the public just want bland. That's what they want to buy. I think online purchasing has driven some of that, Simon Cowell has, and we seem devoid of anything inspiring. But there is inspiration folks - it is there, but it is underground.
That's why I tune in every now and again to bands that I linked above (Shame), and others like War on Drugs (the track,Ocean beneath the Waves, is one of the best tracks I have heard this century) and Future Islands. There are a few others, but not the swathes I used to look towards in the past.
Sorry, this is way off topic. As you see, I have a bit of a passion for music, but not only the bands that form it, the concepts through time. I'll get off stage now!
