Congratulations (Roomie, PewDiePie and Boyinaband song)

In mid-2018, the subscriber count of the Indian music video channel T-Series rapidly approached that of Swedish web comedian and Let's Player PewDiePie, who at the time was the most-subscribed YouTuber.[9][10] As a response, PewDiePie fans and other YouTubers had shown their support for PewDiePie, while T-Series fans and other YouTubers had shown support for T-Series, in the PewDiePie vs T-Series competition. During the competition, both channels had been gaining a large amount of subscribers at a rapid rate. The two channels had surpassed each other in subscriber count on a number of occasions in February, March, and April 2019.[11][12][13][14][8][15]

The song's popularity caused PewDiePie to gain 168,000 subscribers on 31 March, and 309,000 subscribers on 1 April.[18] This caused him to overtake T-Series that day, ahead by a peak of 512,000 subscribers on 8 April.[19][20] The effects of the video soon wore off, however, as T-Series overtook PewDiePie again on 14 April 2019.[21]

The day after the song was uploaded to YouTube, PewDiePie regained his lead against T-Series, although he lost the lead for good to which he tweeted "big lol" on Twitter, posting a screenshot of the subscribers count.[22]

Eight days after it was released, "Congratulations" was banned in India, alongside PewDiePie's earlier diss track, "Bitch Lasagna". The Delhi High Court granted an injunction against the two songs at the request of T-Series, who asserted the tracks were "defamatory, disparaging, insulting, and offensive" and that the songs contained "repeated comments... abusive, vulgar, and also racist in nature." In their decision, the court noted that PewDiePie, in communication with T-Series after the release of "Bitch Lasagna", had apologized after posting the first video and had "assured that he [was] not planning any more video[s] on the same line."[23][24][25]

In August 2019, it was reported that T-Series and PewDiePie had settled their legal disputes outside of court.[26]

A music video for the song was released the same day. The video was previously recorded in November 2018 in anticipation of T-Series surpassing his subscriber count.[27] It shows PewDiePie, Roomie, and Boyinaband throwing a party inside a room adorned with party decorations, balloons, champagne, and a cake that imitates the T-Series logo. They sing and dance congratulating T-Series in a tongue-in-cheek manner. At the bridge of the song after the second verse, PewDiePie gives a "Thank You" to all his fans and subscribers for supporting his career and gives a "Brofist" to the camera, before the video cuts to the final chorus of the song with a scene showing PewDiePie, Roomie, and Boyinaband launching fireworks outside in the night. The video ends with MrBeast giving a slow clap to the song. As of December 2020, the music video has received nearly 202 million views.[28]
