Ok, so it’s like this…our boys listen to the music we like (don’t judge – sometimes there is some inappropriate language but we have had the “art and artists and expression and just because you hear it in a song doesn’t mean you get to repeat it” talk)  They are old enough to get it and appreciate music. 
They also don’t get a lot of the words right or listen closely enough so when they wanted to “sing” on video, I jumped at the chance.  Pretty funny stuff.
