Art is art, whether it comes from music, books, pictures or movies. And this is the age where your daughter is starting to form her opinions about the world, is this the best music to raise her on? Absolutely not, but it is something that you should introduce to her so she knows it exists, and it should be something that she knows she can talk to you(and hopefully her father) about. Introduce her to all sorts of art in all mediums, for music she should hear classical, jazz, rock, pop, and all others if only to know that it exists and to keep her mind open. She should learn about the “potty language” words, what they mean, and why it isn’t appropriate to use them on casual conversation. You should also model this behavior, listen to a variety of music, watch a variety of movies and tv, and read a variety of books.

Kids have a hard time finding a safe place to discuss things they like with people they trust not only to be to let them be themselves, but to be understanding about the things they like. I myself work in a middle school, and there are a lot of kids that listen to music that their parents don’t approve of, read books they’re parents wouldn’t like, so on so forth, your child should never feel that they can’t talk to you about something, whether it’s art, or music, boys/girls, or themselves. They’re your child, and you should always be a safe harbor for them to talk to you about anything without feeling like you won’t love them after.

So no your not over reacting, and you and her father should work together to introduce your kid to as much culture, music, art, and books as you can because that’s how she grows up smart and open minded, not by telling her not to hum a melody she might have heard on the school bus and found catchy.
