There have not been a lot of animated county music videos. I can think of a lot of artists who are very cartoonish but few have made cartoon themed videos.

Lonestar broke out the 'toons in 2004 when they released "Mr. Mom" and made an entertaining cartoon out of it. I still love this one. Check out the video here and I added Brad Paisley's cartoon video for "Crushin' It" which is highly entertaining as well.
