Depends on your opinion of maturity
If you're even wondering if this song is appropriate for your kids, you're obviously new here. If you have ever heard a song by these artists, you should already know the answer. Language can definitely be expressed as a problem. Swearing every other line, it has quite a bit of consumerism. I don't think consumerism is your biggest problem in the song, though. It requires a mature audience. It's really up to you whether or not your child can listen to this song. Your child could be 17 but completely immature, or eleven and acting like an adult. If you really need an age related suggestion, i would say 13 or 14? I shouldn't even be listening to this song to be honest.
