You’re going to hear “All I Want for Christmas is You” roughly 100 times before the holidays are over. Even if you try to avoid it. Oneboredjeu Mashup took it to another level of on YouTube. They decide to mashup Mariah Carey with My Chemical Romance.
Just because you can do something, doesn’t mean you should. If you want to give it a listen. it’s below. But, remember you can’t un-hear it.

Don’t say you weren’t warned.
