Why do people who play loud music with the car windows rolled down ALWAYS listen to shit music? It's either rank drum amd bass, some gangsta rapper shouting about how he's gonna pop a cap in yo' monkey ass or appalling dance/soul drivel in the Craig David mould.
I think it's the same social process as sodcasting tinny music from your mobile phone on public transport. Every now and then you do get someone who's too incompetent to use headphones or showing a video to a friend, just as you do occasionally come across people listening to proper music (or speech) with the car windows open in hot weather.
But the overwhelming majority aren't doing it to listen to the music, they're doing it to dominate the space (possibly out of fear as much as aggression), and the choice of music reflects that. It's the audio equivalent of manspreading, and it's no coincidence that the perpetrators are overwhelmingly young and male.
I've yet to work out which category tinny music leaking from implausibly loud headphones comes under.
But even as a veteran of
ukc.misc, I can't explain the phenomenon of Craig David.
