It so happens that the album is one of my favorites as well.  You may recognize the cover of Hayes Carll's latest album from it's starring role on the 2011 iTunes television commercial, it's there from about :16 to :18, he's the awkward looking fellow in the red, white and blue sweater.

There's another commercial out there somewhere, where it plays a more prominent role but I couldn't find it.  Anyways check out his acoustic performance of the title track 'KMAG YO YO' and if you enjoy it, check out the video for his current song 'Another Like You' which you can hear on Radio Texas Live every Saturday night.  Here's the vid!
