Jericho's words and his actions do not keep time with the music. One of the greatest wrestlers to ever grace a wrestling ring. He needs to stick with wrestling.
Your low iq is showing. It's evident that it's lip synced not just based off the unnaturally perfect pitch of the vocal, and the sonically modulated nature of the voice indicative of the post pitch processing that is apparent within the studio version of the recording, but also based on the sonic quality of the vocal track overall. He is singing through a cheap dynamic mic plugged into a cheap preamp into a loud pa system, and yet what we hear is the sonically lush vocal characteristics with a crispness that any audio engineer, like myself can immediately detect as a condenser mic recorded in a studio through expensive equipment. To make it even more dreadfully obvious, this same level of quality is not apparent when he actually is using the mic in his hands. Plus you can hear through the camera mic him actually singing the part very out of pitch and often out of time with the more dominant backing vocal in a few moments. He's got a unique voice, don't get me wrong. But he is not a technically proficient singer. And he is lip singing here
