On the what do the kids listen to topic ...
I have three
My 12 year-old listens to the Spice Girls and Jewel. She says thanks when I give her Nanci Griffith and Waterson and McGarrigal and Pogues disks and then never plays them (so I take them back and play them myself).
My 10 year-old ignores all music as far as I can tell.
My 8-old listens to Beethoven and Carmen.
