James Corden might have brought carpool karaoke to the mainstream, but the United States Olympic Swim Team just perfected it in a glorious video posted ahead of the 2016 Summer Games.
40 athletes, including superstars Michael Phelps, Missy Franklin, Ryan Lochte and Nathan Adrian participated in the epic karaoke session, which included tunes from Justin Bieber to Flo Rida.
While some songs were clear misses (R.I.P. "Call Me Maybe"), others were undeniable crowd pleasers (i.e. Fifth Harmony's "Bo$$").
And everyone unanimously sang to America's other National Anthem, Miley Cyrus' 2009 smash hit "Party in the U.S.A."
