10 Best WWE Theme Songs From CFO$

4. Sami Zayn - "Worlds Apart"

Sami Zayn would often show up in street clothes during his promos backstage and in the ring in NXT. He'd almost always wear punk rock band t-shirts before his own tees began filling the merchandize stands and WWE Shop's website. 

His debut song, "Lower the Boom", was a rap/rocker not unlike Rage Against the Machine or the Beastie Boys. Considering Zayn had plenty of punk rock cred, this didn't make much sense for him at all.

Then, when CFO$ redid a good portion of the NXT roster's theme songs, Zayn was upgraded to "Worlds Apart," the punk/ska jumper that fans go crazy for today. The second you hear that "whooooa," you know you're in for a great night of wrestling. 

Besides, it's impossible not to feel happy when listening to this song no matter what's going on in your life. This theme is probably the most upbeat in WWE or NXT. Just imagine how triumphant and wonderful it will be to see Zayn return to in-ring action early next year with this song heralding him in.
