A line from Wah Keung Chan's Montreal Gazette music review of a Renee Fleming concert: "...the Mehldau songs were plagued by the sameness of most 20th-and 21st-century compositions -lacking rhyme, rhythm, melody, and ultimately reason." Seriously? Most 20th and 21st century classical music lacks rhythm, melody, and reason?
I guess many 20th/21st century composers wanted to turn away from melody. But many "modern" pieces do have melodies, maybe just not ones that every music reviewer enjoys or recognizes. And certainly, most 20th/21st century music has rhythm! And I'll bet that if music lacked reason, it wouldn't be composed.
And I don't think most recent music sounds the same, not at all.
Of course, this is the same reviewer who thought "crescendo" meant "climax."
