Here’s a behind the scenes that looks into the making of Justin Bieber’s new song Boyfriend, which is also co-written by my buddy Mike Posner.

I’m not a fan of mash up’s, but DJ Earworm puts a lot of work into them. It won’t kill me to highlight his newest work. He somehow manages to mix all these songs together:
