No. Like Poppymama said, considering my own musical tastes, it wouldn't work. My 11 year old lives half the week with me, her stepdad, and downstairs she has my sister and her husband. At her dad's house, the other half of the week, she has her dad and her stepmom. Excluding her step parents, all the adults she spends time with have all worked in the music industry 15-20 years. There are a huge variety of tastes, she has a library of over 3000 cds to choose from, and she is careful enough to ask me if something is "appropriate." My answer is, if it's making you uncomfortable, turn it off, think about why. We talk about music and why certain things are "offensive" and maybe shouldn't be shared with classmates. Her tastes run from Pink Floyd to The Killers to David Bowie. She doesn't like rap much, which is probably a good thing considering most of ours is old NWA and the like.
She doesn't understand why her dad and I love Slayer, and I don't understand her infatuation with Brandon Flowers. But it all works out.
DD has never been into any of the teeny-bopper bubblegum pop stuff - hated Miley Cyrus and her ilk - but I wouldn't have "banned" it if she had liked it (though I would've insisted on headphones).
On the other hand, my 5 year old sings along to Rammstein (in German), Talking Heads, DEVO, and Lady Gaga. He also loves Miranda Cosgrove, but you can't win 'em all.
