I think it's more a case of Modern Life is Rubbish
We're just bombarded with stuff that has been pre-selected "for you" to fit a demographic profile. Everywhere you look stuff that you don't really want or need is pushed in your face. In years gone by, when there were far fewer advertising channels and no internet, it was simpler to ignore.
Music is just another commodity to be parcelled up nicely and sold to the sheep-like masses, or carefully-targeted niches. It's a natural by-product of the information age and it's harder & harder for most people to resist the tide of shite, whether it be fashion, music, so-called lifestyle products, or any other consumer item.
Heartily agree with you there Palerider. I hate this thing where, if you buy something from Amazon, you are then the victim of "others who bought this CD also bought ...." Half of the time it's a totally irrelevant 'choice' - I always want to reply along the lines of "it wasn't for me, it was for my mum nah nah na na nah!". Should teach me to buy in shops instead of on line I guess?!
