Embarrassed? Heck no. I love all kinds of music. I've sung everything from medieval motets to Carmina Burana (of O Fortuna fame--the city choir is singing that with the symphony in a couple months--epic!) to Wham to Wang Chung to John Denver & The Muppets Christmas album (12 days of Christmas is hilarious!).
Now, I HAVE managed to embarrass my KIDS by turning up Lacuna Coil, Skillet, Epica, Evanescence, and Kamelot really, really loud in the minivan while the windows were rolled down in the summer time, breeze blowing through the windows, and singing at the top of my lungs. It's fun to see the people in the cars next to me with that
look as their brains try to process seeing a mom rocking out in a mini-van.
