And rap & hip-hop.
It's funny that people who don't like a type or genre of music find it to "all sound the same".
The key here is that the overpowering dislike of the genre precludes recognition of subsets and differences between songs.
I dislike... somewhat passionately... the music most define as "standards". I suppose that careful listening would reveal that Fred Waring is quite different from Benny Goodman or Guy Lombardo, but the fact is that I don't want to dissect something that I universally can't tolerate. So I also make the blanket statement that all standards sound the same.
The fact is that rap & hip hop does not sound the same, nor do "standards" even if I can't make the distinction personally.
