Did you expect anything but an amazing end to the 2013 iHeartRadio Music Festival considering Justin Timberlake was the closer? The Renaissance man consistently lives up to his hype, and his performance Saturday night (Sept. 21) was no different -- but it did inflect some new elements, including two brand new songs.

BFF to another Justin (of the Bieber variety) Floyd Mayweather introduced Timberlake as "the heavyweight champion of music," a title he rightfully won. The '20/20 Experience' singer had a set lasting twice the length of his fellow performers', ending past 1AM PST.

Timberlake was accompanied by a 15-piece band for the set, which ended with two new tracks from 'The 20/20 Experience - 2 of 2.' One song, 'True Blood,' may or may not be inspired by the HBO vampire sex epic series, and 'Only When I Walk Away' made the crowd wish he'd never walk away from the mic stand ... unless, of course, it was to dance.

Also, watch the clip above closely -- you may be able to see a really awkward Jessica Biel trying to dance herself. (Love you, girl, but leave it to the pros!)

In short, Timberlake took back the night from the newcomers (and, well, the not-so-newcomers). And Hell if he didn't take it rightfully.
