everything was better in the past! payphones, slide rules, having no internet with which to complain about the present, and my personal favorite was watching poor quality recorded programs on an impossibly complex VCR...on my non-HD TV.
The ultimate proof that the past isn't so different from the present, nor future (at least in music) is that despite all the great music that came out in 1969...the #1 song of the year was...........Sugar Sugar, by archies. Bear in mind that this is the same year that come together, and get back, by the beatles came out. So no, shit music is not a modern phenomenon. You just need a few decades to filter out the bad stuff.
