We are abroad and all songs on the radio contain the full explicit lyrics which means I now do try and censor what the DS hear because some of it is really full-on and I don't want to get into too many discussions about song lyrics like these:
Talk Dirty - Jason Derulo
"Sold out arenas, you can suck my penis (SUNG REALLY LOUDLY)
Gilbert Arenas, guns on deck
Chest to chest, tongue on neck
International oral sex"
which was on non-stop last year.
However, I was quite pleased with DS1's misinterpretation of that Robin Thicke song - when he keeps singing "you're a good girl, you know you want it", he said, that's about a dog isn't it?
I said, err, think it's a woman, and he said, no, that's how you talk to dogs.
And of course he's right!!! 
Not quite on topic OP, but thought it might make you smile!
