BTS ARMY took over Twitter on the day of the 63rd GRAMMY Awards with #LightItUpBTS.

An initiative to show support for the global superstars' first-ever GRAMMY nomination, as well as BTS' first time to perform their own song at the show, the hashtag garnered millions of tweets even before the main ceremony began. 

Here's a list of BTS' performances of 'Dynamite' – watch

BTS were nominated for Best Pop Duo/Group Performance for their smash hit, 'Dynamite,' with the award eventually going to 'Rain On Me,' by Lady Gaga and Ariana Grande. The IFPI Global Artist of the Year winners made history with the nomination by being the first Korean pop act to be nominated at the GRAMMYs and in the category.

Ahead of the show, BTS leader RM shared a message to ARMY via an interview with USA Today: "There are so many blessings we could've gotten for these eight years, but I guess for the whole journey the best luck we ever had is that we all have you guys all over the world. So please don't forget that, whether we get the Grammys or not, we already got what we wanted, and we got you, so that means we got everything."

The track, penned by David A. Stewart and Jessica Agombar, which also sits number 10 on IFPI's Global Digital Single Chart, is the group's first English song and has received numerous awards in Korea and abroad. It serves as BTS' first Billboard Hot 100 number 1 hit and has broken and set several records including being the most-viewed YouTube music video in 24 hours. As of press time, the official music video is on its way to 1 billion views.
