Canadian country music, Martina McBride, Barbra Streisandplaylists

Will there ever be a Canadian country music playlist? I have found several Canadian country artists in other playlists. I was just wondering if you have ever thought about making a playlist for them. Also, how about a Martina McBride playlist? That would be awesome! I already have 3 of my other favorite country artists as playlists. She would be awesome. What about a Barbra Streisand one as well.
