VIDEO : Eminem and Gwen Stefani Release New Song 'Kings Never Die' for Southpaw

Eminem has blessed us with another song from the Southpaw soundtrack, and it is phenomenal. But this time he teams up with Gwen Stefani. With a duo like that, fans could only assume great things, and they both delivered.
Titled "Kings Never Die," the song has the intense, motivational beat that Jake Gyllenhaal could probably use while staging his comeback in the upcoming movie. As if that weren't enough, the lyrics also will get your blood pumping and will pretty much make you ready for anything, whether it's a boxing match or running five marathons.
