And when the dominant US culture is referred to, we refer to Anglo American culture, not English American. Latinos have shortened it to Anglo, which also gets used a lot. Just not by the Anglos/Anglo Americans themselves. That is how the rest of us refer to them.

In the US, "folk" music is a genre of music associated with Anglo dominant culture more than any other. The rest of us refer to our own music traditions as "German" music, or "Italian" music. The folk hybrid is a British thing, and only really popular amongs the British North Americans, and those who have assimilated into that culture, or the real Anglophiles. One need only watch the Oscar show to see how alive and well Anglophilia is in the US.
