As far as cussing goes, I guess it depends on the targeted audience. I of course resent bad language aimed at young kids but more than that, I wouldn't want to see them exposed to 'problematic' ideas and themes. Censorship is good wjen it aims at protecting young minds from evil influence, but it often poses as holier-than-thou medieval morals.
I personally don't think such a word is a serious offense in a Country song, but I'm extremely shocked to hear and see what I very often hear and see on hip-hop radios and TV channels. Apology of crime, violence and porn on a grand commercial scale are often tolerated if not encouraged. So I'll let Zac put his ass on the sand, it doesn't threaten anyone IMHO.

PS: of course I'm from France, a country famous for its lax morals all over the world ;>D
