How about suffragette songs?

Colonial songs. And more.

So much blues,jazz, bebop, etc music is from the "northern region".

And labor songs like those mentioned at the Wiki Wobblies page. And then check out their List of protest songs page!


Then there is the treasure trove at the American Memory website's California page.

This Wiki page
has samples of different Native American tribal songs from the north/midwest/west. And even more.

Wiki also has this brilliant page that not only gives an overview of American music history, but clickable links for music from all 50 states! How cool is THAT?
