I believe America has long been heading towards an almost totally non-involved music scene. Add to that the almost religious fervor for the bottom line (hire the cheapest entertainment you can

), and you can see how almost ALL the general public's music making is relegated to karaoke, where even THAT is primarily ONE person singing, and everybody else just watching, or Guitar Hero and Rock Band 'air guitar' faking...
Communal singing is pretty much non-existent (at least by European standards). Listen to any soccer match... (except over here!). They never STOP singing..! Maybe it's the culture of individualism, maybe it's the cutting back of school music programs (for decades), but it IS a shame that Americans don't like a good old sing-song.
Any US musicians got an explanation for why we hate to sing (as a nation)?
