Do you jam out in the car with the windows down?

I'm pretty sure I can't sing worth shit. Was at a red light on my way home from work today and Seven Nation Army by The White Stripes came on and I'm rocking out because, well... I like the song. Look over and this little boy and girl probably pre teens were smiling And giggling. No way it could have been because of me. I'm a freaking rockstar #noshame.
