This is "Feriado Nacional" by the Mexico-Argentina favorites Kumbia Queers (who first popped up in here in mid-'07). It's another genre-bending track about the glories, or necessity, of not working.
True role models, as far as I'm concerned. I know that headache. Are we need of an a la chingada with it all, pan-Latino-style work revolt? Play it!
