I grew up reading music/movie reviews religiously. Sometimes the 'critic' was right on and other times I disagreed with their assessment but all in all, everyone has a distinct right to their own opinions. I have tons of classical music in every conceivable format but have realized that unless you're a musician, a musicologist or are adept at reading music, what endears me to the piece is my reaction, positive or negative to the piece.
I also LOVE melody. A lot of music, especially country, has that worn out feeling. It's been done to death. Unless a piece stands apart from the crowd......I try to avoid it.
Rock music, IMO, had a more challenging aspect to it in the 60's and 70's. It was, IMO, a golden age when melody flourished, the concept album was born and musicians were inspired by the muses which informed them. I'm sure there is a wealth of new music available today but as I don't avail myself of radio or watch video's anymore [who does?], I profess ignorance.
I watch a lot of those late night shows and when they highligh a particular artist ........ I watch ... and listen ..... but have hardly been moved in the last few years to say ..... WOW ..... brilliant! Is it just that I'm jaded or is it possibly that the acts got smaller.
After all, Billy Joel,Elton John and most iconic rock bands of that 60/70's time frame are just coasting along on the hits which made them famous decades ago. So, really, it's all about that MUSE. Once it abandons the artist ........ it's either time to retire or reinvent oneself ....... and as we all know .... NOT an easy task.
