To Tell The Truth?

My wife wants to make CDs for my 10-year-old daughter for Christmas. One for each of us, containing all of our favorite songs. I'm wondering, should I be honest and include songs like Metallica's Master of Puppets? Or shelter her from my angry music tastes of yore and only include songs that are age appropriate?

If you had to choose one song as your all-time favorite, what would it be? I'm thinking about it.
