One of the great things about music is that musicians steal. And we mean that jovially because another way of saying it is that people are influenced by other cultures and ideas. If you listen to Scott Joplin you hear classical influence. If you listen to Django Rheinhardt, you Roma and jazz coming together to do something astonishing. In his song Hung It Up, Junior Brown does riffs borrowed from a bunch of his favorite guitarists, including Bill Haley, Dick Dale and Jimmy Hendrix.
There is an ocean of music in the world and the Internet has taken every style to every city and hamlet around the planet.
