Explicit Lyrics

So, are lyrics explicit if you can't understand them? I don't think they sang Hollaback Girl live since that sounds like Gwen Stefani's voice. It's pretty clear she sings "Uh huh, this my sh*t at around 17 seconds into the video. It's not really that big of a deal... I have the MP3 of the album in my iTunes. However, the song (this version anyway) has a EXPLICIT tag on the iTunes store. This happens a lot when Korean singers try to be all gangster and include the English "bad" words in the rap.

I just wonder if the PD (producer) knows that he/she began this huge year end show with an English cuss word. What if a contestant on American Idol decided to sing a K-pop song and added a bunch of Korean swear words? What would the crazy Korean netizens say?
