well - considering that "US culture" is an amalgam to begin with -

never mind - I'll ignore the fact that this seems to be a thinly disguised US bashing thread and address the issue as stated.

For myself - I am interested in the source of songs - it is intrigueing to find out known authors of songs that you see listed and listed over again as "trad" - and likewise to find copies 150 to 200 years old of songs copyrighted in the 60's and 70's. The country of origin doesn't matter much to me if a song interests me - but it can be an interesting addition to the song. "Irish" songs that orginated in the US or in England. "scots" songs by English authors. US ppop songs with souyth American, Caribian or African roots.

heck - I'll steal from any source.
