On August 30, Abba made its official Tiktok premiere, and to describe their success on the platform since then, words like "millions" and "billions" must be used.
New songs and the new studio album Voyage, which was released on Friday, have hardly diminished the hype.
Tiktok themselves believe that a number of Abba trends exploded even before the group itself appeared.
#DancingQueenChallenge, where users challenged each other to try out the group's legendary vocals, has resulted in over 160 million video views.
Tiktok is largely a song and dance app, which suited Abba.
Tiktok is usually described as an app for children and young people, and that dusty adults do best in staying far, far away.
But, the 70-plus in Abba have obviously been warmly welcomed.
