Apparently the biggest battle of Super Bowl XLIX wasn't between the Patriots and the Seahawks.
The new, 40-second trailer for Pitch Perfect 2 dropped at the end of the first half of Sunday's big game and featured a whole lot of aca-awesome singing battles, including a "Bootylicious" performance by the Packers (which is totally better than playing in the Super Bowl). It was also the only Super Bowl ad to prompt viewers to use Snapchat.
