The Music Dilemma

The kids love the listen to the radio in the car and I often hear "turn that up" from the back seat. Kate Perry's Hot N' Cold is one of their favorites.
Most of the time my radio stays on XM because you can't beat commercial free right? I am careful to switch the station if the song might be inappropriate and mostly when Brandt and Campbell are in the car we listen to Mix 22.
Then came Brandt's iPod. We simply downloaded Will's itunes (without editing) and gave it to him. All 730 something songs. He and Campbell have always loved the Girlfriend song (Avril Lavigne - the edited version). Now he also loves Shake Your Rump.
Last week he asked to download a song. He knew what it was called and everything. It was the Black Eyed Peas - Boom Boom Pow. Great for a 6 year old, right?
The only thing better than that was to hear Campbell singing from the back seat "hush girl, shut your lips, do the Helen Keller, and talk with your hips", while Ryan and I drove to dinner. Yes, she knew all the words. I had to go home and ask Rachel who even sang the song. (3OH!3, if you are wondering).
To top it all off, on the way home from a birthday party, Brandt asks me if I know the song that goes "Nah, Nah, Nah, Birthday and a really bad word?" I don't, but I knew which song he was talking about. He assured me that he sings it "Birthday text, you know, like you are sending someone a text message, Mom." Great, I feel so much better. Where are you hearing this?
