Canada's iTunes Music Store is finally offering a Free Single of the Week download! The free singles have long been available thru the US and British music stores, however this week Canadians finally get to hear one new artist every week at no charge. The very first free single is by Vancouver's "Be Good Tanyas". The song is called "Opal's Blues" from the soundtrack of the movie "Because of Winn-Dixie". It is promoted as "an intoxicating mix of old-time country and blues, folk, bluegrass, and gospel." So at that price, how can you go wrong?
