This album isn't appropriate for the tween girls who sing along at shows. I say this only because the girls see it merely as a pop album with words, they don't actually listen to the lyrics.
If you raise your children to understand and listen to the words in songs, then this album is not only okay for them to listen to, but I believe an album that should be listened to, with at parent.
This is an album filled with songs about addiction and self-hatred, a cry for help. More kids need to hear things like this to see that alcohol and drugs aren't as much fun as they often sound to be.
