JUST WATCH IT.
Best Metal mashup ever, for some reason it just fits..
Note: I'm not the maker, don't know who is but this vid is really awesome and I needed to share this one!
Metal mashup, original songs from:
Justin Bieber - Baby &
Slipknot - Psychosocial
Personally no fan of both, but together they should make an album!
Please enjoy, all credits to those who made it!
