Recently I've come across Jamendo.com, a site where amateur musicians from all over the world can upload their work for others to listen to and download free of cost (mostly. You can make donations, but they are purely voluntary).
Lots of great music there, and the tags system makes it easy to search for your favorite genres. Even combinations of your favorite genres.
I'm recommending this because I've found a lot of really cool music there, and you guys might, too.
My personal favorites include Diablo Swing Orchestra and Leslie Hunt, but there's something for everybody there. Dig in. Enjoy.
