An interesting comment on Plastic, speculating on
how a war would affect popular culture.
Basically, during war, escapism and propaganda become dominant, with
dystopian sci-fi/serial-killer films and gothic rap-metal likely to be
replaced with feel-good light comedies and syrupy torch songs, alternating
with rousingly black-and-white propaganda and stirring patriotic anthems
(picture Celine Dion singing God Bless America across the airwaves on heavy
rotation; yes, I know she's Canadian, but so's most of the US entertainment
industry), and anything edgy and uneasy would not be well received (does this
mean that Radiohead's career will come to an end?).
In short, the Top 40 of tomorrow will be your grandkids' ironic retro kitsch.
