#1. Former WWE Champion John Cena
John Cena is not only one of WWE's biggest Superstars but he's also a major celebrity. The 16-time WWE world champion has starred in many movies and he was also involved in the music business.
During his early run with WWE, John Cena was known as The Doctor of Thuganomics and his entrance theme, Basic Thuganomics, was a song that he performed. He also released a full-length album in 2005 called My Time is Now.
After dropping the gimmick, Cena became a more family-friendly character and he used one of the songs from his album as his new entrance music. The song was such a big hit that even people who don't watch wrestling are familiar with it.
The fact that the Leader of the Cenation has had it as his theme song for this long indicates just how iconic it is. Every time the theme song hits, fans immediately know who it is and they hilariously mock Cena in harmony as the theme blares throughout the arena.
